Managing your moisture is crucial to staying warm during a day on the slopes, and the piece of clothing most responsible for doing so is the one touching your skin. So, pull on the Under Armour Men's Base 2. 0 Legging for moisture management and next-to-skin comfort. As Under Armour's mid-weight baselayer, these leggings perform across a wide range of weather conditions, which makes them a solid choice if you're looking to own just one baselayer set. The four-way stretch polyester absorbs sweat and dries quickly, while the ergonomically placed flatlock seams ensure chafe-free comfort. The fly allows for quick relief after hydrating and can be utilized for ventilation on sunny spring days.
