Ideal next-to-skin winter comfort - Smartwool Merino 250 Baselayer Bottom - Men's

Fits perfect on a 5'10" 200 lb frame. Not too snug, but not loose anywhere. I workout five days per week and consider myself of average build. Runner and weightlifter.

These wool bottoms are ideal for winter backcountry travel. They remain comfortable next to your skin and don't get stinky. I find synthetics, although they actually dry out faster, to 'feel' damp after exertion compared to merino wool. And they can smell after a few days of wear. Not so with these bad boys. Pair with merino wool undies and a top and you're good-to-go for the week. Smell-free and comfortable unless you get them dirty.
