Here's what other sites are saying:

After working up a sweat while you hike for fresh turns, a frisky, cool wind can quickly lower your core temperature and send you running to the lodge. Avoid that scenario with a little help from the Under Armour Men's Base 3. 0 Crew. This baselayer supplies enough warmth for cold days on the mountain, absorbs sweat, and dries quickly so you don't feel chilled between runs. Not to mention, the 3. 0 Base is equally big on comfort. Snug-fitting four-way-stretch polyester allows you to move with complete freedom, and the flatlock seams ensure you'll stay chafe-free throughout the day. Plus, the anti-odor technology keeps the man-stink away so you can head into the lodge without clearing it out.
