Nothing is quieter then wool. That is my main problem with the new gear. If it is waterproof it is noisy. Wool is far from being water proof, but I can be wet and still warm. You also learn to stay dry. Light rain isn't that big a deal, hard down pours find a tree and see if it passes. I go to the store convinced I am going to purchase a new Gortex piece of gear from one of the new companies but always leave empty handed when I remember how noisy they are.
Wool is back in style. Lightweight, base layer Merino wool is so much better than heavy wool. Layers are better than one thick jacket or pant. Plus it dries better and is soft as cotton.
Wool has always been great but the "new" wool has really taken it to the next level. Stretchy, quick drying, comfortable and better dyes too.
