With its do-everything-design, the Under Armour Men's Base 2. 0 Crew provides moisture management and warmth across a wide range of temperatures and weather conditions. The 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. Additionally, 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.
