For nearly four years, I have been taking the Hyperlite Mountain Gear Prism pack for most of my alpine climbs, whether that be on rock, snow, or ice. After that long of throwing the pack on my back, here are some of the pros and cons that I've experienced while using it.

When it comes to camping in the deep cold, staying warm is the ultimate goal. But did you know that organizing your gear in your tent can make a huge difference? Here are some tips on gear organization to maximize heat retention.

Just like understanding the tradeoffs between single- and double-walled tents, it is equally important to understand the basic differences in single- and double-boots when we head up for an alpine climb or mountaineering attempt. While the differences between specific boots will be varied, there are some general differences between boots with and without removable liners that I keep in mind when selecting a boot for a climbing adventure. Here is what I consider when deciding what to put on my feet.

For over a decade, I've been using the same split finger gloves (or split finger mittens) as a compromise between the warmth of a mitten and the dexterity of a glove. They aren't right for every trip but I can use them in a surprising amount of situations. Here's a video on some of the pros and cons and how I choose when to use them.

Famed high altitude mountaineer Ed Viesturs has used two-person quilts on the highest mountains in the world. Backpackers often use quilts, now, as a matter of course. So, my family has been using the two-person Enlightened Equipment Accomplice sleeping quilt for backpacking and for alpine climbing, both to add warmth (body heat of a second person) and cut weight (less per-person weight). This video offers a product review.

If we are out on a backpacking trip or an alpine climb, we are already counting ounces. More efficient canister stoves tend to be heavier. So, how many days of fuel use need to happen before that efficiency and saved fuel pays off when compared to carrying a lighter, less efficient stove with, therefore, more fuel? We did a first test in summer conditions.

Camping comfortably can mean the difference between being restored every night of our camping, backpacking, or alpine climbing adventure, and reaching our goal, or slowly getting drained to the point where we have to quit. One of the first things to consider about our camp strategy is whether to take a single-walled or double-walled tent. Here are some of the pros and cons of each.

Our boys, now age 8, have been using the Deuter Climber 22 Liter Kid's backpack for over three years. It's been the pack they take on just about every hiking, backpacking, camping, and climbing adventure. So, with that much wear and trust put into the backpack, we thought it would be worth a review. Here's what we dislike, like, and love about this pack.

I don't feel like my family and I should be pushing our limits with hard climbing all of the time. We had previously done a video about learning to find satisfaction with some of the less demanding forms of adventure so that our risk profiles aren't always high. Well, exposing the boys to backpacking was one of those experiences we wanted them to try and see if they enjoy. We made a short film about it.

My twin (now) 8-year-olds beat up their gear when they are camping, hiking, and attempting summits, but we've managed to keep them in an Outdoor Research Kids' Helios sun hat for about two years. The hats are still going strong, but like any piece of gear, they aren't perfect. Here's a long term review of these handy, comfortable, and durable adventure hats.

Transferring canister fuel from one canister to another may save you money, weight, or both as you prepare for your next climbing, backpacking, or camping trip. But, it's not without its risks. In the video, we review the FlipFuel transfer device and demonstrate how to use it.

When we go climbing in the winter, take on alpine climbs in the shoulder seasons, or go to high altitude, we are likely to face camping in the snow. If we are going to keep a camp at a single location for a longer period of time, or if we are facing whipping winds, we may want to build snow walls to better shelter our tent. Here's how to build them.

Climbing big mountains in anything more than a day, may demand that you cold-weather camp as well as you climb. It's the key to your recovery at the end of each day. My twin eight-year-old wanted to try winter camping in truly cold weather. It got down to -6 F (-21C). Here's what I was thinking about and focused on teaching them during these 48 hours out.

For the past two winters, I have been experimenting with battery-heated gloves as I've gone out camping, hiking, and climbing. Like all niche gear, they are good at some things and not so good at others. Here is a full review of the Lenz Heat Glove 6.0 Finger Cap.

When we go climbing, camping, or hiking in the backcountry during the winter, we tend to stay out longer and experience more extreme conditions. As advances in technology have improved battery-heated gloves, are they now able to perform well enough and long enough to make them worth having in your gear closet?

Ice climbing usually demands a lot of different gloves. Different portions of ice climbing need more dexterity and therefore less insulation. Some portions are the opposite. Some portions expose your hands to a lot of water. Here's how the approach ice climbers use to pick gloves to bring can help us think through how different gloves, in combination, can help us ensure our kids have warm hands on their climbing, hiking, and camping adventures in winter.

A cottage brand out of Japan, Locus Gear, has made a free standing, ultralight, dome tent with four-season toughness by producing a fabric combination of Dyneema and eVent. It's called the Djedi. After using it for a year on camping trips, backpacking trips, and alpine climbing trips, I'm providing a full review.

A climbing partner from Denali (seven years ago) put together a trip for the Skillet Glacier route on Mount Moran (12,605') in Grand Teton National Park. She and I embraced hiking the long approach, bushwhack off trail, and 6000 feet of elevation gain to get our fill of summer snow climbing on a direct and impressive line.

Spring time in the Rocky Mountains means snow couloir season for climbers, and this year, we figured out how to get technical crampons to work on the boys' small feet. So, the boys and I took a short camping trip that culminated in their first real alpine snow climb, including a few small snow fields before a 500 vertical foot gully. They learned the mental and physical persistence that direct snow lines can demand, and I was admittedly in awe at their incredible capabilities while being so young.

Knowing which gear works best for your climbing, mountaineering, backpacking, hiking, and camping trips is harder than it seems. But lessons learned from the scientific method and the discipline of product development can help ensure that you are improving your gear systems each time you head out.
