Bamboo and cotton are both terrible materials especially in winter. Not only to they absorb sweat. But they do so in a way that would kill you in the winter and would make your garment rather filthy in the summer in short order.
We could really use Nylon and gortex in game. But some folks poopoo the idea. Also merino wool. In short, camping gear. Waterproof, breathable, cool in the heat while warm in the winter.
The 2 materials I ONLY wear. Nylon and Merino wool. Nothing less than 75% merino will do! Else it really doesn’t work. Well Gortex I suppose I use too. But nylon with a high denier is usually cheaper >_>
I’ll go make a idea thread for this.
