Women's Lightweight Underwear

Lightweight long underwear isn't an oxymoron. The long-sleeved tops in this range will keep the sun off on a long desert hike or Yosemite big-wall, without being sweaty or constrictive. The tights are great for when you need just a little extra warmth under a pair of hiking pants, and they can also be worn directly under waterproof pants on warm, wet days or alpine expeditions, or you can use them as sleepwear when camping. With excellent brands like Patagonia and Smartwool, all the garments on this page are ideal for keeping you comfortable on moderate or warm trips outdoors.
