Reusing those plastic bottles from a beverage purchase may leach BPA into your water (maybe a topic for another video). But I also know from many conversations that some people will do it anyway because it can save money and weight and they don't do it that often. Well, for those of you who are willing to accept the risk, there is also a practical consideration: the lips on the mouths of those water bottles can melt when pouring boiling water making them unable to be closed. So, you can take this simple, light, piece of gear to avoid at least that problem when backpacking or camping in the winter.

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). The full video goes into what I was thinking about and focused on teaching them during these 48 hours out.

Some climbers have moved away from using the Prusik hitch to the Klemheist hitch as a friction hitch on the rope because they are easier to tie (especially with gloves). Although a Klemheist can have varying degrees of bite on the rope in different directions of pull, unlike a Prusik. That has led to the question: "What if I accidently tie a Klemheist backwards?" As long as you dress it, the "backwards" Klemheist becomes a Hedden hitch, and is still effective.

The girth hitch, or larksfoot, master point climbing anchor has come into vogue, with climbers extolling the virtues of their ease to tie and untie along with the minimal gear needed to make them. But, like all things in climbing, there are pros and cons to these climbing anchors, and we need to understand the strengths and weaknesses of some of our options when we construct them.

Should you damage your climbing harness, you can improvise a new one with a sling, a few carabiners, and the climbing rope. Here's one solution for a harness that will provide both seat and leg support.

Are a-threads or v-threads stronger? What makes a "threaded" ice climbing anchor strong in the first place? In the full video, we go a little deeper into the characteristics of stronger and weaker threaded anchors and go through a tutorial of how to build a good one.

Anytime you need to stay upright while using a vertical rope - including crevasse rescues to rock rescues - you may want a chest harness. Here are two options using a simple 120cm sling and a single carabiner, and a quick discussion of their pros and cons.

When we form a rope team for glacier travel on a mountaineering route, we need to get the tie in points placed efficiently. While we may make different decisions on how far apart to place climbers based upon the crevasse sizes, the mix of terrain, and communication difficulties, we will always end up at the need to divide the rope and tie the knots where we want them. The full video provides two methods for doing so.

If you need to be able to come out of the rope easily, like during a crevasse rescue, you may tie a Kiwi Coil one way. If you need to temporarily shorten and then lengthen the rope, you may tie a Kiwi Coil another way. If you are going to stay tied in all day, like for mixed alpine climbing, you may want to tie a Kiwi Coil this way.

If you've ever had a carabiner freeze shut or freeze open, you know how troubling or potentially dangerous it can be. While we always want to try to find the right carabiner for the job, when we add in snow, ice, and cold we need to also consider how resistant our carabiner styles are to freezing. The full video shows an experiment I ran to compare how well (or not well) different gate styles stood up to harsh, cold conditions.

When on a rope team and needing to pass your knot through a piece of protection, like during a running belay, you want to be as safe and efficient as possible. Here's one technique to accomplish those two goals.

Knots weaken soft climbing materials like slings, but we tie knots in slings all the time. Particularly the high forces that anchors can face during multi-pitch climbing will make us want to be sure our anchors are reliable. So, why do so many people tie knots in anchor slings? And isn't this worse with dyneema? The full video goes deep into this topic.

While I typically do ensure that I have tent stakes with me for my winter camping and alpine climbing trips, it's good to know what makes good winter tent stakes so that you can improvise one, if need be.

Over 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. The full video reviews the Lenz Heat Glove 6.0 Finger Cap.

I carry chemical warmers in my first aid kit for cold weather climbing, hiking, and camping excursions. But I only buy the toe warmers, not the hand warmers. Here's why.

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, the full video explores if they are now able to perform well enough and long enough to make them worth having in your gear closet.

When we are out climbing, hiking, or camping in cold temperatures, we need to layer well. And our layers need space between them to insulate. That means our liner gloves need to strike a balance between cold protection and being thin enough to work with your outer gloves, too.

Winter peak climbing has its own unique challenges. Borrowing from my winter mountaineering experiences on Colorado 14ers, Colorado 13ers, and my climbs around the world, the full video shares what new winter climbers can expect so that they may better prepare themselves for the challenges of summiting in the coldest months.

Steep snow climbing up often means steep snow descents. When heading downhill, the snow conditions often dictate what types of steps will keep you upright and more secure. Here we talk about the Plunge Step for use on soft snow.

Ice climbing, and particularly mixed climbing, sometimes demands that the climber switch which tool is in which hand. There are lots of ways to switch hands on your ice tools, and all of them have pros and cons. The full video breaks down three different techniques and then lets you know which one I typically use and why.
