I hear that canister stoves don't work in the cold a lot. But I've also used canister stoves in the cold a lot, and so have many other climbing teams who head to the coldest corners of the globe. However, it could be that there are times that canister stoves make more sense and times liquid-fuel stoves are a better option. This test of eight different stoves sheds some light on how the knocks on canister stoves are overstated as well as circumstances where liquid-fuel stoves might make a better choice.

Blue Ice took a really good harness and redesigned and rebuilt it, anyways. Is the new version of the Choucas Pro harness enough of an improvement over the older version to earn a place in your gear closet?

Two years ago, I did a video about the potential I saw in 3M Gripping Material as a wrap for ice tools. Two years later, now, I have found one version of the material to be not good enough and another version to be pretty good, but at a cost.

After one year of use and one big expedition in Asia, I've learned enough about the Samaya Ultra 60 pack. Here's what I've found to be the pros and cons along with a few modifications I've made to my pack.

Climbing at three miles (4800 meters) above sea level can be a challenge for out body's physiology. Having access to almost as high of peaks in Colorado, here is how I spent the final month before my trip to that three-mile altitude to ensure I showed up pre-acclimatized to the altitude along with a discussion about why intermittent trips up to altitude can still help acclimatization.

High altitude peaks bring many hazards, from rock fall to avalanches to seracs to crevasses, and many people would count weather among those. But when we think about weather, we are often concerned about storms and cold. Well, the cloudless days with perfect weather bring UV rays and sun damage that are way more significant than we experience at the altitudes at which we live.

Flextail makes the Zero Pump and claims it to be the lightest self-contained pump for both inflating and vacuum deflating your backcountry sleeping mattress. I purchased my own and tested it out over multiple seasons. Here's a full review of the pump and my take on circumstances when carrying this into the wild makes sense for me.

A trip plan can keep you and your climbing partners on the same page but also can help your loved ones deal with any emergencies that might arise. So, what can we put in our trip plans to ensure we meet these needs?
