As the Under Armour Men's Base 1. 0 Legging 's name suggest, this baselayer is designed to cater to your basic need for warmth and four-way stretch performance when skiing. Made with a moisture wicking fabric, the Base 1. 0 Legging absorbs sweat and dries quickly. Not to mention, the 1. 0 is the lightest baselayer offered by Under Armour, which makes it ideal for spring slush and moderate weather. The flatlock seams ensure chafe-free comfort against skin, and the working fly allows you to quickly relieve yourself after slugging a cold one.
