>>2804989It's good advice parroted by retards.
The problem is that cotton fibres reduce their surface area when wet, basically collapsing on themselves. That destroys their insulation and makes them dry very slowly.
It's not an issue when it's hot, or when you wear cotton as a shell layer with proper insulation beneath it. But if you rely on cotton insulation in winter, you're gonna have a bad time. You'll sweat (which, unlike what some of the /in/ crowd on here claim, isn't bad on its own), the sweat will soak the cotton, and you'll freeze.
>Doesn't waxed cotton repel moisture, including snow?Yes, but waxed cotton also doesn't insulate well and isn't breathable. a waxed or oiled cotton jacket in winter will collect condensation on the inside.
>what type of jacket is bestWool felt. Fur is a close second, with it's only disadvantage being that it's not breathable. On both of those, the hair fibres will adjust to sweat to some extent, reducing their insulation just slightly and allowing your body to manage it's temperature properly.
Synthetics can work, too, but they always insulate about the same (unless absolutely wet), so you're either a little cold, or constantly sweating. On the other hand, they dry much quicker than wool, meaning that if you have enough water and minerals to compensate for the excess sweat, they're fine.
>>2807681>t. /inDidn't we have that discussion just last month? Sweat evaporates slower the older it gets, and wool, fur and synthetics still insulate when wet. While I won't deny that stewing in your own sweat is uncomfortable, it won't kill you, or even do any harm beyond causing acne or rashes (after multiple days to weeks, so not an issue the average guy will face).
