Review: Sea to Summit ThermoLite Reactor Extreme

I had such high hopes for this product. The Reactor Extreme is a ThermoLite sleeping bag liner and the label indicates that it can add up to 25°F of warmth to your sleeping bag. These liners have a shelf price around $65. My purpose for buying the liner was:

  • Use it as a very light sleeping bag in very warm summer weather
  • Augment my normal sleeping bag in seriously cold conditions
  • Use it in conjunction with an emergency space blanket bivy in my Bugout Bag

I tried the liner at home first. I keep my bedroom pretty cool at probably about 60°. I tried sleeping on the top of my bed using only the liner. It was not nearly warm enough. The material is thinner than many of my T-shirts and it felt about as warm as a single bedsheet (perhaps a thin flannel sheet). I was hoping that it would be much warmer. On the second night I slept under my bed comforter only. I woke up at night and then slept under the comforter and in the liner. I did not feel any warmth differences when I used the liner.

There are many advantages to using a sleeping bag liner. If you are sweaty and dirty then the liner will take the brunt of your untidiness and you can easily wash it. It should also provide added warmth. I had another liner many years ago and it was larger but you could definitely feel the warmth difference. The Reactor was a complete disappointment but with performance and especially with price. I would venture to guess that a cheap, compressible fleece blanket would provide much better performance than the Reactor. I read other online reviews that gave the Reactor a high score but my experience was just the opposite.

The Reactor Extreme is made of very soft and comfortable material. However, I do NOT recommend it because it is expensive and I feel no appreciable warmth difference. If you are a hot sleeper then perhaps this product might work for you. For me this liner was about as effective as a single-ply bedsheet. I read positive online reviews of this product but my experience with it was not positive.

Review: Leatherman Micra & Style

I include a very small Leatherman multitool in each of my first aid kits. The small Leatherman tools include scissors, a small knife, screwdriver, and fine tweezers. The key tools for me are the scissors, tweezers, and small knife. Scissors can be used to cut bandages or do other fine cutting work. The tweezers and small knife are very useful for removing splinters and other fine work.

Leatherman makes two very small and high-quality multitools, namely, the Micra and the Style CS. Both tools are very similar.

Micra Features

  • Spring-action scissors
  • Clip-point 420HC knife (1.6″, 4.06cm)
  • Tweezers
  • Nail file/cleaner
  • Screwdrivers (3): small, medium, flat phillips
  • Bottle Opener (420HC steel)
  • Ruler in inches/metric)
  • Lanyard Attachment
  • Weight: 1.75 oz (50g)
  • Length (Closed): 2.5″ (6.35cm)
  • Materials: 100% stainless steel (Optimum grade hardness for each tool/blade)

Style CS

  • 420HC Knife (1.6″, 4.06cm)
  • Spring-action Scissors
  • Flat/Phillips Screwdriver
  • Tweezers
  • Nail File
  • Carabiner/Bottle Opener
  • Weight: 1.4 oz (41.1g)
  • Length (Closed): 2.9″ (7.5cm)
  • Materials: 100% stainless steel (Optimum grade hardness for each tool/blade)

Both of these tools are typical Leatherman (excellent) quality and both would be a very functional addition to your kit. I attach mine to the zipper pull on my first aid kits to make them easy to find and use. Keep the tool easily accessible because you will use it for small jobs such as cutting cloth or removing splinters. A small multitool is NOT a substitute for a larger multi-tool. It should be used in addition to your main knife and multi-tool. Do NOT compromise on a lessor tool but get a quality and precision tool that will last for many years.

Recommendation

The Micra and Style CS are very small and well-built multi-tools that includes spring-action scissors and a variety of other tools. A lanyard allows you to easily attach them to key rings or zipper pulls. Both are built with legendary Leatherman quality. Both of these tools are excellent and you really cannot go wrong either way.

I prefer the Micra over the Style CS multi-tool but choosing one over the other is a tough choice. The Style is slightly lighter and I like the carabiner feature. The Style also allows access to some of the tools while closed. The Micra has non-removeable tweezers while the tweezers on the Style must be removed and can get lost. Because of the integrated tweezers I prefer the Micra over the Style CS.

I secured my Micra on a ring and attached the ring to the zipper pull on my first aid kit. This way I access the Micra quickly. The most valuable features of the Micra (in my opinion) are the scissors and tweezers. My larger multi-tool is better for tools such as screwdrivers and knives. The small, precisions tweezers have removed many splinters. The scissors are useful for cutting first aid tape and cloth.

Review: Leatherman Rebar & Sidekick

The Leatherman Rebar and Sidekick are lightweight multi-tools packed with features and Leatherman quality. These two multi-tool are very similar so I combined them for this review.

The Rebar packs 17 tools into a compact, stainless steel body. Unfold the Rebar to access the pliers and the other tools. The body of the tool uses rounded edges to make it more comfortable on your hand. The Rebar includes a nylon sheath.

The Sidekick includes 17 tools in a compact, stainless steel body. The large knife and saw are accessible when the tool is folded. The other tools can be accessed with the Sidekick is unfolded. The pliers and wire cutters are spring action and stay open by default. Most other Leatherman multi-tools do NOT stay open. The rounded edges on the tool body make it even more comfortable to use than the Rebar. The Sidekick includes a large, rugged metal clip but NO sheath.

Rebar includes:

  • Pliers: needlenose nose and regular
  • Replaceable Wire Cutters (2): 154cm regular, 154cm hard-wire
  • Electrical (2): electrical crimper, wire stripper
  • Knives (420HC): straight blade & serrated blade (blade length 2.75″)
  • Wood/Metal File
  • Saw
  • Screwdrivers: Phillips, small slotted, large slotted
  • Awl with Thread Loop
  • Ruler: 8″ / 19 cm
  • Bottle Opener and Can Opener
  • Lanyard Ring
  • Strong, nylon sheath
  • Weight: 6.7 oz.
  • Length (Closed): 4.0″

Sidekick includes:

  • Spring-Action Pliers: Needlenose and Regular
  • Spring-action Wire Cutters (not replaceable)
  • Wire Stripper
  • 420HC Knifes: Straight and Serrated (Primary Blade Length 2.6″)
  • Saw
  • Ruler: 1.5″ / 3.8 cm
  • Can Opener and Bottle Opener
  • Wood/Metal File
  • Screwdrivers: Phillips, small slotted, large slotted
  • Large metal clip (no sheath)
  • Weight: 7 oz / 198.4 g
  • Length (closed): 3.8″ / 9.7 cm
  • Large clip

Rebar and Sidekick include the Leatherman 25-year no hassle warranty. All of the tools in the handles securely lock into place. You must manually unlock a tool to stow it back into the handle. I personally want a multi-tool that includes a wood saw. The Rebar and Sidekick are lightweight, compact, and they have a very useful complement of tools and features. I purchased a Leatherman Super Tool many years ago and it has served me well over the decades. If I were buying my first multi-tool I would seriously consider either the Rebar or Sidekick because they are a little smaller and lighter and they have the tools that I would most use.

Rebar Advantages:

  • Larger saw
  • Replaceable wire cutters

Sidekick Advantages:

  • 420 steel blades
  • Spring-action pliers
  • Blade and saw can be access while closed
  • Slightly more comfortable in the hand
  • Large clip that makes it easy to attach in a pocket

Review: Cabela’s E-VAC 2CR-123

The Cabela’s E-VAC 2CR-123 is a small, durable, tactical flashlight powered by two CR-123 batteries. It features a push-pull head to adjust the beam from very wide to very narrow. I have the older version that outputs 300-lumens and the current version generates a 500-lumen beam. This flashlight is manufactured for Cabela’s by LED Lenser, a respected and reputable manufacturer of high quality flashlights. The E-VAC is a little larger than I prefer as an everyday carry but it would make a very nice belt flashlight. The beam color is more white than other lights, such as the Streamlights. The light pattern is very even and there is no noticeable hotspot in the center of the beam. With the focusing collar pushed in the E-VAC produces a square-ish beam pattern . When the head is extended it produces a very large and even beam. Package contents include:

  • E-VAC flashlight with batteries installed
  • Heavy nylon sheath with closure flap and beltloop
  • Lanyard cord
  • Instructions and warranty papers
  • Two spare CR-123 batteries

The included belt sheath is quite nice. Most flashlight sheaths are made from soft nylon fabric and these ordinary sheaths are function but unimpressive. The E-VAC sheath is actually one that you would purchase if it was not included with the flashlight. These are some of the pro and cons for the sheath:

  • Good: Heavy reinforced and rigid nylon with heavy stitching
  • Good: Velcro closure for fast open/close (better than snaps)
  • Good: Elastic sides for a secure fit
  • Good:Small loops on the top of the elastic sides for added attachment points
  • Bad: Belt loop does not hold sheath securely when removing flashlight

I like the matte metal finishing on this flashlight. My Streamlights are fantastic lights and they use a smooth and more polished finished. The E-VAC has a less polished finish giving it a dull, black appearance. This dull finish gives the light a more grippy feel that feels secure in my hand.

  • Construction: Machined aluminum with aggressive front strike bezel
  • Size: 5-1/2 to 5-5/8″ long, 1-1/8″ head, 7/8″ body
  • Waterproof: IPX4 water resistant
  • Light Output
    300-lumen: High (300 lumens) for 6 hours, low (20 lumens) for 20 hours, strobe
    500-lumen: High (500 lumens) for 2 hours, low (60 lumens) for 3.5 hours, strobe
  • Batteries: 2 CR-123 batteries
  • Beam Pattern: Very even beam with no hotspot
  • Beam Focusing
    300-lumen: At 3′ it generates a 14″ square zoomed and 48″ diameter on wide
    500-lumen: At 3′ it generates a 17″ square zoomed and 54″ diameter on wide

Operation

Operating the light is different than what I am accustomed to. The flashlight switches between high, low, and strobe modes. With my other flashlights I activate the light and it always generates the high beam. I can then click to low and strobe modes.

The E-VAC operates differently. If you activate the high beam and turn it off then the next time you turn on the light it will be in low beam. If you turn it off and on again it will be in strobe mode. If you want the light to always generate the same light pattern then you must click the button twice with turning it off (to cycle through the unwanted modes). Turn off the light when the LOW beam is showing and the next time to activate the light it will be in STROBE mode. Off in HIGH beam and next ON will be LOW beam. Off in STROBE and next ON will be in HIGH beam.

Tactical Use

The E-VAC has a more aggressive front strike bezel. I generally do not like focusable flashlights for tactical use because the sliding head can severely pinch you if you strike with it while the head is extended. This flashlight is a 5.5″ long and the main body section is about 3.25″. This length is sufficiently large to keep my palm away from the sliding head if I am careful. If you have large hands then you must be aware that the sliding head could severely pinch and injure your hand. If you retract the head for tactical use then you will generate a highly focused and intense beam and reduce the risk of pinching your hand. A highly focused beam could be both a blessing and a curse depending on the situation. The beam will be much more intense but will extend over a much smaller area.

Non-Tactical Use

The beam patter is focusable and very even making this an excellent inspection light. For example, if you are buying a house then buy this light and bring it when inspecting prospective homes. The wide and even beam pattern will allow you to easily see flaws in walls, floors, and cabinets. The focused beam will allow to inspect attics and crawl spaces and see greater distances. If you need to inspect machinery then the power and even beam pattern would make this an excellent flashlight to use. I also use this flashlight when photographing dark spaces such as old buildings and forts.

Advantages

  • Runtime of 6 hours on high is longer than similar flashlights
  • Dull finish makes the flashlight very easy to grip
  • The focused beam throws the light for a considerable distance
  • Semi-aggressive bezel would make it an effective tactical weapon

Disadvantages

  • I do NOT like the way the flashlight cycles through the light modes
  • The sheath is sturdy but it can be difficult to remove the flashlight quickly
  • The octagon on the tail of the flashlight is unnecessary and makes it difficult to remove the flashlight from the shealth
  • Elastic on the inside of the sheath makes the flashlight difficult to remove

Recommendations

There are other lights that I prefer as an everyday carry (EDC) light but this is a very nice flashlight to add to my collection. The sliding head allows you to focus the beam for greater distance. I purchased this flashlight specifically for photographing dark places such as old military forts. I wanted a light with an even beam and plenty of light output. This flashlight is also excellent for inspections. If you are purchasing a house then you might want to use this light when inspecting houses. The strong and even beam pattern makes it easy to see imperfections in walls, molding, floors, etc. If you need to inspect vehicles then this might be an ideal light your you. This flashlight has a much longer runtime than most lights that use two CR-123 batteries. If you want a nice light to carry on your belt and you want a focusable, even beam pattern then the E-VAC is a good choice.

Review: Duracell 350

The Duracell 350 is a stout aluminum body flashlight that generates 350 lumens. I purchased a 4-pack of these lights from Costco for $20. My expectations were not high but these are surprising nice flashlights. The 350 uses three AAA batteries mounted in a cylindrical battery holder. The body of the light is fatter than most flashlights but it has a good feel in my hand. The knurling, heat sink bands, and fatter body combine to create a very good grip. When held in my hand the light is wider than my palm and it could be used tactically. The front strike bezel is fairly aggressive. I keep one at home and one in each car. It would not make a good everyday carry (EDC) light because of the size and it does not include a clip. I would recommend these flashlights because they work well, are bargain priced, and they use standard batteries. I would not purchase these for the Amazon price but if you can find them at a discount at Costco (or similar outlet) then they are worth the price.

  • Construction: Machined aluminum in a variety of colors
  • Size: 4.5″ long x 1.1″ diameter body with 1.3″ diameter head
  • Waterproof: IPX4 water resistant
  • Features: High, low, and strobe modes
  • Battery: 3 AAA batteries
  • Light Output: (high) 350 lumens at 5,000 candelas for 1 hour, (low) runs for 4 hours
  • Beam Pattern: At 3′ the total beam pattern is about 44″ with a 7″ hotspot

If you cannot find the aluminum version of these flashlights at a good price then consider the DuraBeam 350. I have not tried these but they look like a polymer version of the 350. The specifications look very similar and Duracell generally makes very good products.

Recommendations

Purchasing a 4-pack of these lights for $20 from Costco is a no-brainer. Put one in your car, have one in the house, and you could even use one in your hiking kit (if your headlamp uses AAA batteries). For a hiking kit I would prefer a flashlight with a longer runtime but 4 hours on low is still respectable. There is nothing fancy with this flashlight. It is just a good, economically priced, and capable flashlight.

Review: Streamlight Stinger HPL

The Streamlight Stinger HPL is a large, durable, ultra high-power flashlight, that uses a single 75375 NiMh rechargeable battery to generate a 800-lumen beam at 48,000 candelas. This is NOT an Everyday Carry or concealable flashlight. This is a large flashlight that is about 9.2″ long, weights over 13 oz., and includes two charging docks. This type of flashlight is intended for heavy use environments in demanding conditions such as first responders, security professionals, safety personnel, etc.

This is a heavy use service light that includes two charging docks. Many users will use one dock in a vehicle and the other in an office. The battery life is 1.25 hours on full power. When not in use the flashlight is normally stored in one of the charging docks.

  • Construction: High impact polymer body
  • Size: The HPL is large at 9.2″ long
  • Waterproof: The Stinger HPL is rated at IPX4 water resistant
  • Features: High, medium, low, and strobe modes
  • Battery: Replaceable 75375 NiMh battery
  • Light Output: (high) 740 lumens at 48,000 candelas for 1.25 hours
  • Beam Pattern: 35″ x 4″ at 3′ (Beam Scale)

Recommendations

This is NOT a normal household flashlight. This flashlight is intended for heavy, everyday use. The beam pattern is tight with an extremely intense hotspot. The dual chargers allow the light to be recharged in both an office and vehicle. In the hands of a trained user this heavy duty flashlight would make a formidable weapon.

Review: MSR Guardian Water Filter

The MSR Guardian is an amazing device that filters contaminants down to 0.02 microns. Most other filters filter to 0.1 – 0.3 microns. While these “normal” filters are fine for most applications they will NOT filter the ultra small organisms such as viruses. The MSR Guardian WILL filter most viruses and it can be used to filter extremely fouled water. If you do a quick internet search you should be able to find this filter for around $350.

The Guardian is portable and lightweight (only 17.3 ounces). It can filter 2.5 liters of water per minute. The Guardian pump filter is self-cleaning and about 10% of the pumped water is used to continuously clean the filter. The filter lasts for 10,000+ liters. A hose allows you to pump water from a stream other water source. The Guardian retails for about $350 and a replacement filter costs about $150. This filter can be used by backpackers or anyone that needs to filter a larger volume of water quickly. If you are in an emergency situation where the water supply was compromised then you should use a 0.02 micron filter such as the MSR Guardian. This is also an excellent choice if you travel to remote locations with questionable water quality.

Threads on the bottom of the Guardian connect to wide-mouth bottles such as Nalgene bottles. A duplex hose reaches from the filter to the water source. One of the duplex hoses is the water intake and the other is the flush line. About 10% of intake water flows over the ceramic filter to continually clean it. The cleaning water is then pushed out the flush line on the duplex hose. The clean, filtered water drops out of the bottom of the Guardian into a wide-mouth bottle.

Advantages

  • Filters water to 0.02 microns (most other filters are 0.1 – 0.3)
  • Continuous cleaning as water is filtered
  • Filters high-volume of water quickly (2.5 liters/minute)
  • Hose allows easy access to water source
  • Portable and less than 18 ounces
  • Filter water directly to a wide-mouth bottle

Disadvantages

  • Unit and filters are more expensive than other filters
  • Filter life good but less than other filters such as the Sawyer

Conclusion

If you want a serious water filter then this is one of two that I recommend. For a gravity filter consider the Sawyer Zero PointTWO. If you need to filter higher volumes of water quickly then the Guardian is an excellent choice.

BioLite

The BioLite cooking system is a very innovative product designed to solve two problems at once, namely, cooking and electricity. The BioLite stove includes an internal fan for extremely efficient burning, a power pack that converts heat into electricity, and a mounting system that supports a variety of optional attachments. Attachments include a portable grill and a large KettlePot. The BioLite can burn almost anything combustible to generate heat and electricity.

Advantages of the BioLite system include:

  • Can be powered by almost any combustible material
  • Generates electricity and has a USB plug
  • Can accept a grill, kettle pot attachment, or lights

Disadvantages of the BioLite include:

  • Weight: the BioLight is heavier than most camp stoves
  • Less efficient than comparable gas backpacking stoves
  • Larger in size
  • Small firebox requires adding fuel often

I am not sure what to think about the BioLite system. It is definitely a very cool concept. Being able to cook, generate electricity, and not require store bought fuel is a very appealing concept. However, the BioLite is large and heavy compared with other cooking systems and you can generate electricity more passively with portable solar panels. The small firebox means that you will have to add fuel often. If it takes a few hours to charge a device then you will have to babysit the stove to ensure that it does not run out of fuel. I would prefer to have a solar charger that I could “set and forget.”

If you are going to be extremely remote and have no way to obtain fuel then the BioLite makes sense. For normal backpacking the BioLite is simply too large and heavy to be practical especially for solo trips. While being able to use any combustible fuel seems appealing there are ultra efficient gas stoves that use very little fuel and are much lighter. There are also lighter stoves that can burn any biomass fuel.

Review: Streamlight ProTac HL3

The Streamlight ProTac HL3 is a durable, ultra high-power flashlight, that uses three CR123 batteries to generate an 1,100 lumen beam at 36,000 candelas. At 7.4″ long and a head diameter of 1.6″ this is a larger flashlight. The HL3 comes with three CR123 batteries, a tactical belt holster, and sells for about $80. The aircraft aluminum body of the HL4 is the same diameter and uses the same tail cap as the HL. It will NOT use rechargeable batteries.

The HL3 tactical light generates a remarkable 1,100 lumens at 36,000 candelas. The front and rear have semi-aggressive strike bezels that would make an effective weapon. The body is very comfortable to grip. Many of the other Streamlights such as the HL, PolyTac, 1L-1AA produce a beam with a very hot center and the light decreases significantly towards the outer edges of the beam. The HL3 has a very noticeable hotspot but it produces a brighter and more even beam for the entire diameter of the beam.

  • Construction: The HL3 is machined from aircraft grade aluminum, has semi-aggressive striking bezels on both the head and tail, threads are tight and smooth, and sealed with an O-ring.
  • Size: The HL3 is large (7.4″ long) and would work well on a service belt.
  • Waterproof: The HL3 is rated at IPX7 waterproof.
  • Features: Has high, strobe, and low modes. You can also change the light mode using the Ten-Tap programming feature.
  • Batteries: Uses three CR123 lithium batteries.
  • Light Output: (high) 1,100 lumens at 36,000 candelas for 2 hours, (low) 35 lumens at 1,200 candelas for 43 hours.
  • Beam Pattern: 40″ x 7″ at 3′ (Beam Scale)
  • Power Fail: No low battery indicator and the flashlight will significantly dime when the CR-123 battery gets to 2.84v.

Things I like about this ultra high-power flashlight:

  • The beam pattern is very nice. There is a definite hotspot but entire diameter of the beam is bright
  • While this is a large flashlight it is still a manageable size for a utility belt
  • Nice tactical belt holster included

Recommendations

If you are looking for a high-power tactical light then this is a good choice. This would be a good choice for first responders that do not use the light extensively. The CR123 batteries are still a bit expensive and with a runtime of only 2 hours on high power it could get expensive to operate if it were used extensively.
