The largest mistake that new winter hikers make is overdressing by sporting heavy or medium-weight baselayers which are laborious to take away for those who begin to sweat. You’ll be a lot better off sporting a really skinny crew or quarter-zip shirt and including extra thermal or wind-blocking layers on prime of it for those who begin to really feel a chill.
For instance, you’ll be able to exert a finer diploma of management over your heat stage for those who put on a light-weight baselayer prime as an alternative of a medium or heavy one after which add a second light-weight prime over it for those who begin to really feel a chill. There’s nearly no weight distinction clothing-wise on this strategy, but it surely provides you a a lot finer stage of management over how heat you need to be when mountaineering in winter.
Perspiration is Unhealthy
The issue with being too heat in winter is that it causes you to perspire. Perspiration is dangerous as a result of it burns extra energy, however that’s a tough idea for most individuals to grasp and internalize. A extra apparent final result is that perspiration causes the air pockets in your clothes to clog up with liquid. This reduces the scale of the air pockets in your clothes that entice heat air, decreasing their means to insulate you.
Some perspiration is inevitable, even when your physique is at relaxation. Known as insensible perspiration, you’re physique emits about 400 ml of water per day via your pores and skin. The Greeks had been the primary folks to watch this reality 1000’s of years in the past.
Layering
When you can’t fully cease perspiration, you’ll be able to handle the diploma that it degrades your clothes’s insulation worth by sporting hydrophobic clothes that transports any water it absorbs away out of your pores and skin. This strategy, generally referred to as layering, is finest completed by sporting skinny, extremely porous clothes subsequent to your pores and skin. When layering, you need to protect that wicking motion via as many layers as potential. The objective is to maneuver moisture out of your pores and skin to an outer layer the place it could actually evaporate.
For instance, I exploit three core layers in my winter mountaineering layering system:
- A skinny light-weight lengthy sleeve jersey, often artificial.
- A light-weight fleece hoody
- A nylon windbreaker
That’s it, all the way down to about 15 levels. I can inform it’s working as a result of the underarms of my wind shirt are damp and pungent on the finish of the day. Meaning my perspiration is evaporating from the outermost layer.

The Subsequent-to-Pores and skin Layer
I’ve discovered that a very powerful garment in my layering stack is the foundational next-to-skin garment. Search for tops which you can see via whenever you maintain them as much as the sunshine. I desire artificial long-sleeve tops as a result of they don’t take in as a lot moisture and are very efficient at wicking moisture as much as my subsequent layer. Wool can work too, particularly wool clothes that mix artificial and wool yarns as a result of they wick like artificial tops however odor much less on account of their wool content material. They’re additionally way more sturdy.
Listed here are the next-to-skin tops that I exploit and that you simply would possibly discover helpful to attempt.
However I can’t stress this sufficient. Hold that next-to-skin layer skinny in order that moisture can transfer rapidly via it and up into your subsequent layer. Whereas it’s not intuitive, you’ll keep hotter for those who keep cooler and perspire much less through the day.
