What defines mountain weather and why does it matter for rain jackets?
Welcome to the Backpack and Light Podcast, where we investigate the intersection of science and technology, gear design, and wilderness experience to help you develop a deep foundation of true backcountry expertise. In today's episode, we are searching for a rain jacket to keep you mobile and safe in a mountain storm. And a hint, it's not exactly ultralight, but it's light enough. Hello everyone and welcome to the Backpack and Light Podcast. I'm your host, Ryan Jordan. Today's episode is a companion episode to the recent article we published called Reindear for Mountain Minimalism. I will put a link to that article in the show notes for reference, but otherwise, let's get right into today's topic.
Look for me in the mountains where walking. Has a way. Pulling you to your peace of mind every day.
Today we're talking about range gear for mountain minimalism. This is going to be a little bit different than how ultralight backpackers typically look at range gear. I want to start by defining what I mean by mountain weather. There is a point where your rain jacket isn't just this emergency item that sits in the bottom of your pack. It becomes part of the system that keeps you mobile in hostile conditions. So when I'm thinking about mountain weather, I'm thinking about being above the tree line where you're exposed to wind and rain and wet snow, and there's no protection from trees or forests. You may be dealing with poor visibility, you might be dealing with lightning, maybe you're dealing with terrain where stopping for a long time just creates more problems.
And that's one of the real challenges with mountain environments. You often need to keep moving. You can't always stop and wait it out. There may be no shelter up there. There you might be exposed to more hostile weather, and you're probably in a location where the better decision is often to keep moving until you can reach a more protected place. If I'm going to weather a storm, I want to weather that storm down in the forest where there is some natural protection and a sense of coziness. I I don't want to do it up on an alpine plateau with a bunch of storms rolling through. Now I've been in this situation many times, and my preference is not to sit around and wait it out. My preference is to keep moving so I can reach a more protected location.
That's the goal of a mountain minimalist rain shell. It preserves my ability to move and that changes the criteria. That is required for me to choose the appropriate shell in this situation. Some of the questions I like to ask is: how hard is it to manipulate the zipper? Maybe I have cold hands, right? How hard is it to adjust the hood around my face so I can control ventilation and protection more so than I can in an ultralight jacket? How does the shell protect me from? Sideways wind driven rain or snow. To what extent is the fabric pressed against my body by the wind? Or if I have to stop and navigate or put on gloves or make a quick cup of coffee to warm up, do I still have enough protection to deal with hostile, wet, and windy conditions when I stop moving?
That context is not the same problem as whipping out your four or five-ounce jacket from your backpack during a summer shower on a trail. So, before we talk about jacket weight, let's talk about the environment we're trying to optimize for. Most backpackers evaluate rain jackets by weight first. I am guilty of this, right? My summer rain jacket for
How does exposure duration change the requirements for a rain shell?
For mild conditions, weighs like 3.9 ounces. It's really thin fabric, does not have a lot of hydrostatic head resistance. So it's going to reach its limits in a you know hours long sustained storm. But for an occasional summer thundershower, it's great. That is entirely reasonable when I'm in low risk situations. I'm on maintained trails or below the tree line or the temperatures are warmer or the storms are short. I have reliable options to get to other places where I can shelter other than inside my rain jacket, right? I can set up my tent if I need to rapidly. I can hole up under a big spruce tree and stay reasonably dry.
