Platypus Pre-Filter Cap for Sawyer 3 Way SP122 Water Filter

Back in Issue 3 we Reviewed the Sawyer SP122 3 Way Water Filter and since that time I’ve used the filter on several additional trips. It’s still working quite well provided that clean water sources are selected and the water is pre-filtered before using it inline or while in gravity mode. During the review, we tested the SP122 against 100 liters of average mountain stream water (With no pre-filtration) that dramatically reduced the flow rate of the filter. With Sawyer’s 1 Million Gall

Review: BearVault BV450 Bear-Resistant Food Canister

Aside from bear canisters, there are few – if any – pieces of gear that backpackers can be required to have. Don’t want to bring a tent? That’s your choice. Feel like skipping the stove and eating no-cook dinners? Go for it. Trust the forecast and decide to leave the rain gear at home? No big deal. The ability to choose what we bring and the multitude of options for nearly every type of gear that exists are part of the fun of planning a backpacking trip. However, for certain national parks and o

Feathered Friends Hummingbird UL 20 Sleeping Bag Review

For three-season backpacking in most of the continental United States, a 20-degree bag is an ideal choice. When it’s warm it can be used like a quilt, when a late season or high elevation trip has a cold night or two dropping into the teens it will be adequate if not downright comfortable (especially if paired with a down jacket and thick socks), and for nights where low temperatures range in the upper 20s to low 40s it seems perfect. Although I’ve owned 30-degree bags and 15-degree bags over th

Ruffwear Cloud Chaser Dog Jacket: A 14 Year Review

Whether you are venturing out on a day hike with inclement weather in the forecast, or heading out on a multi-day backpacking trip, when you’re doing so with a canine companion taking the appropriate gear not only for yourself, but also for your dog is critical. A dog jacket is one such item that I put to constant use on the trail – nearly every backpacking trip into the mountains – in addition to other dog-specific gear like dog packs and sleeping bags. While there are many dog jackets that wil

Backpacking Gear Lists and the T.R.I.P. Process

The gear list. It might be written on a piece of paper, typed into a spreadsheet, read from a book, or all in your head. But most of us probably have one somewhere. In its simplest form, a gear list can really help with those “I can’t believe I forgot that” moments when you’ve just hiked 20 miles from the trailhead and are setting up camp in dwindling evening light. In other forms, a list can help you identify things you really don’t need, help you reduce your pack weight, and help you identify

MSR WindPro II Stove Review

For 3-season use stove choices are simple: many of us rely on an upright canister stove – with my current favorite choice being the Soto WindMaster. For year-round utilization however and when temperatures fall in winter, and / or melting snow is one’s source of water, modifications to your stove system or a different system entirely are called for. As temperatures drop, performance of upright canister stoves begins to suffer and especially as temperatures approach or surpass the boiling point o

Ruffwear Approach Dog Pack: A 15 Year Review

While bringing along man’s best friend on our backcountry adventures comes with many advantages, especially when backpacking it also comes with an extra set of dog-specific gear. Dog food, a section of foam pad, dog jackets, bowls, leashes, and perhaps even a sleeping bag for your dog all serve to increase the weight carried. The solution of course is to have the dog carry some of their own gear or other gear to help offset some of the weight – most importantly of course without overloading the

Montbell Mirage Down Parka: Long Term Review

If you’re comparing specifications among commercially available light to mid-weight down parkas, one option will surely start to rise to the top of the list as you compare down fill and overall weights across the board – the Montbell Mirage. As a long-time user of their popular and lighter U.L. Down Inner series, and as a backpacker who isn’t afraid to carry a few extra ounces if the comfort trade-off is worth the weight, the Mirage is tempting option for shoulder season and winter trips, or for

Backpacking Jargon: What Are Backpack Load Lifters?

Load lifters are adjustable straps running from the top of each shoulder strap to the top part of the pack body (and ideally to the top of the frame) on many packs designed for overnight carry and beyond. By tightening these straps, the top of the pack is prevented from sagging backwards and a more efficient weight transfer to the hipbelt is achieved by removing weight from the shoulders. An angle of about 45 degrees (running upwards from the shoulder strap to the pack body attachment point) is

Feathered Friends Egret 20 Degree Sleeping Bag Review

Muscle creates energy while adipose tissue stores energy. Energy in this context is synonymous with heat. The female anatomy typically consists of more fat than the male anatomy, especially in the chest and hip area. This is why women are generally perceived to sleep colder than men. Women’s bodies are highly efficient at keeping their vital organs protected and warm, but at the expense of our extremities. When hands begin to ache and toes go numb from coldness, these sensations relay a message

Zpacks Multi-Pack Review: More Capacity, More Convenience

On backpacks, I’m a huge fan of exterior storage. I’ve settled on a popular arrangement: A large interior storage compartment for items I likely won’t need while hiking during the day, a large outside pocket for items I might need when stopped, and dual side and hipbelt pockets for items I’ll definitely need while on the move like water bottles, maps, snacks, and other great to have at hand items. The Zpacks Multi-Pack builds on this idea by adding a large additional storage option with a variet

Tarptent Scarp 2 4-Season Tent Review

When it comes to backpacking gear and especially the big three or four (shelter, sleeping bag, pack, and pad) there are two schools of thought to meeting the needs of different types of trips across the different seasons. On one hand, one can choose to select from an array of seasonally specific choices – for example having 3 sleeping bags with different temperature ratings that ideally fit each trip at just the right weight. On the other hand, one could just choose gear that fits every trip wit

Closed Cell Foam (CCF): Backpacking & Hiking Jargon

In backpacking circles CCF (closed cell foam) is most often used in relation to your choice of sleeping pad, which often comes down to one key decision – air pad or CCF? Both have pros and cons. A thick air pad is found to offer a more comfortable night of sleep for many and they pack small, but care must be exercised to guard against punctures and carrying a patch kit is recommended. And if you want one that’s both light and warm, they can be pricey. CCF pads are warm for their weigh

Coast FL1R Micro Rechargeable Headlamp Review

I’ve always been a fan of headlamps powered by either 3 AAA batteries or a single AA battery (my current favorite). While these types of headlamps may at first seem a bit archaic – the performance is simply there. When it comes to the ultralight headlamp category, lithium has matched, but not overtaken a single AA battery when watt hours are compared side by side. To avoid throwing away batteries, I use all Panasonic Eneloop batteries – rated for over 2000 cycles. On the plus side, ex

Exped REM Backpacking Pillow Review

The Exped REM backpacking pillow is a newer pillow from Exped that's a hybrid air pillow with a layer of foam above. The REM foam layer (That's recycled extracted modules, not the band or the sleep you'll hopefully get) consists of chunks of soft foam that make this pillow a little closer to a non-backpacking pillow you might find at home. The foam layer is all contained in a soft pillow case, with an inflatable air chamber underneath than can be removed for washing or even if you wanted to use

Backpacking Jargon: ASTM F3340-18 & Sleeping Pad R-Value

The American Society for Testing and Materials F3340-18 standard is a standardized way in which backpacking sleeping pads are measured for r-value, or their warmth and insulation value. As a standardized test this allows one to compare sleeping pad r-values on a level field. The test utilizes a cold plate underneath the sleeping pad being tested, with a near-body-temperature warm plate placed on top. Inflatable sleeping pads are inflated to the same inflation pressure. The amount of energy it ta

How to Keep Your Pillow on Your Backpacking Sleeping Pad

We all know a better night of sleep leads to a better next day of hiking. While the most ultralight of pillow techniques calls for using extra clothes, stuff sacks, water reservoirs, or anything you can find all stuffed into another stuff sack, many of us are already wearing the majority of our clothing in our sleeping bag, leading to a bleak build-your-own pillow situation. This case calls for a separate (and more comfortable) dedicated pillow, and with many options now weighing just

Garmin inReach Mini Satellite Communicator Review

Being a responsible hiker means letting someone know where you are going and when you’ll be back. That used to mean (and still does) leaving a note on the fridge. In a world of landlines, this was the best one could do. Once you were out the door, you were out of touch. Needless to say, times have changed. We all have cell phones, and cell phones have become smartphones. Smartphones have in turn become essential hiking tools, combining many functions (camera, journal, compass, GPS, map, trail gu

The Multi-Purpose Foam Pad & Backpacking Sit Pads

Carrying the additional half-pound or so a three-quarter length closed cell foam pad, in addition to an inflatable pad, is antithetical to the general concept of lightweight backpacking. However, the versatility of this piece of gear and the added level of safety and comfort it provides make it something some backpackers never leave behind, with multiple use cases out on the trail – from a sit pad in camp and on breaks, to extra insulation and protection for your inflatable in longer lengths.

Review: PowerFilm USB+AA Lightweight Solar Charger

Disposable batteries are just not ideal for backpacking. After every trip, batteries keep piling up – whether from headlamps, Steripens, or even just from non-backpacking devices we used around the house. Most of the time, getting back from a trip batteries will still have some juice left, but how much? Enough to take along next time? I found myself either installing new batteries for nearly every trip, or taking extras, unless I’d barely utilized the batteries the last time around. Worst of all

Backpacking & Hiking Jargon: Piezo Igniter (Stoves)

A piezo igniter is a push-button stove ignition system that is often integrated directly onto upright canister stoves for convenience and ease of use. The system works via use of a striker that hits a piezo-electric crystal, which generates electricity even when slightly deformed. When the ignition button is pushed the resulting electrical charge generates a spark. With the integrated ignition system there’s no need to hunt down your lighter or use matches – simply open your stove’s g

Vapor Barrier Liners (VBL): Backpacking & Hiking Jargon

A vapor barrier liner is some type of vapor impermeable layer often utilized and effective while recreating outdoors in very cold conditions. By preventing vapor transfer from your body into clothing, footwear, or a sleeping bag for example one is able to boost warmth and keep insulation dry in conditions where wet insulation would be very difficult to dry and result in compromised warmth.

Trail Tip: Using a Backpacking Bear Canister as a Cooler

While a camp stool is perhaps the most popular multi-use application for a bear canister, this tip is best suited for short trips when you're trying to put an emphasis on good food and cold beverages. Bear canisters are a piece of gear added, reluctantly, to the kit of most backpackers only when required for an upcoming trip.

Hiking and Backpacking Jargon: Headlamp Lumens (Light)

Lumens are a unit of measurement used to determine the total amount of visible light emitted from a source. In the backpacking and hiking world, you can use the lumen value to compare the amount of lighting you’ll get from various nighttime illumination sources such as a headlamp. Lumen Considerations / How Many Lumens Higher lumen values typically come at the cost of shorter runtimes and decreased battery life. Brighter lights are also generally heavier and more expensive.
