As Under Armour's mid weight base layer, the Men's Base 2. 0 Crew provides moisture management and warmth across a wide range of temperatures and weather conditions, which make it a solid choice if you're looking to own just one baselayer. Skiing and riding at the resort involve a cycle of sweat inducing activity followed by stationary time on the lift, so it's critical to have a moisture wicking baselayer unless you want to finish the day sweat soaked and chilled to the bone. The Base 2. 0's four way stretch polyester moves moisture away from your skin and dries quickly so you stay dry and subsequently warm throughout the day. Concerning comfort, the bulk reducing raglan sleeves and flatlock seams ensure you'll stay chafe free from the first chair to the last set of turns. Armourblock anti odor technology keeps you from smelling like a high school gym bag so you can grab a cold one at the end of day with total confidence. And of course, you'll get the slim fit you've come to expect from Under Armour.
