Let's talk clothing systems. in The Gear Critic Posted 2 hours ago · Edited 1 hour ago by DanO Layering systems. Plans of usage. There are countless ways to create a clothing system. One would need a gear truck to follow you up the hill to have all the possibilities you may want. Whatever the system need a plan. A plan to stay cool enough. This means a light enough base layer for hiking uphill and when in the sun, or in unexpected warm weather. A plan to stay dry enough. This means a way to dry out , usually at camp. One way is to take off wet clothes and put on dry clothes at camp and do it over the next day.by putting back on wet clothes next morning. Another way is to have a system to dry out clothes via a over capacity in warmth sleeping bag that won't wet out, via a Stephenson's warmlite sleeping bag or a heavy synthetic sleeping bag. A plan to hike in the rain, snow, sleet etc. If using a traditional three layer system that often means a single layer on legs and a base layer with hardshell on top. Likely to get wet no matter what, if warm enough just use the hardshell alone, when stopped shake out the water and put on dry clothes. If intermittent light percipitation a soft shell or base layer alone may be used, body heat driving off excess moisture while moving, especially when hiking uphill. A plan to be warm enough. Most often adding another layer to go over legs and a puffy jacket. If carrying a sleeping bag to be the lightest weight, may do away with the puffy. A plan to dry out while hiking. That means when the rain let's up a clothing system that will dry out by body warmth. A very breathable puffy, let's say a primaloft puffy, or a pertex pile garment. Or a fleece with a breathable windshirt, or a good quality softshell designed to move water out. For legs a thin breathable layer, most likely hardshell off the legs. I find a thin nylon spandex pant works well in cool to mildly cold weather. A plan for a emergeny bivy. A pad and puffy, and a thin sack such as a SOL breathable bivy sack. Or maybe a blizzard bag, or a bothy bag, or a light tarp with fire starter. Ect. Usually just enough to get through the night and be able to effectively move the next day. Whatever the clothing system it is best to have an effective plan for all common situations. If you hike or climb enough, you will have a unplanned night out, or you will be soaking wet and cold, or you will be too hot, all of these and more adverse situations happen sooner or later.
