You should be dressing in layers. I prefer to put on Under Armor next to my skin, followedby a t shirt, then a fleece, then my outer waterproof shell.

On the bottom I wear Under Armor and a pair of wool pants. Wool is the ultimate because no matter how wet or frozen it gets it keeps you warm still.

I wear SmartWool socks.


dressing this way keeps your lower body warm enough. And allows you to take layers on and off as you cool off and heat up from climbing hills etc.
