The Under Armour Spectra 1/4 Zip Men's Mid Layer is a highly-functional, superbly-warm base layer for cold days on the mountain. The Spectra uses a gridded hybrid fleece for optimal breathability and warmth and without increasing the weight. It also wicks away moisture and dries quickly when wet, so you're never left with chilly moisture ruining your day. Perfect as a layer under a ski jacket, the Spectra has a low-profile collar and thumbholes to help keep sleeves in place and trap in warmth. Stay fresh all day too thanks to the jacket's anti-odor technology, which prevents the growth of odor-causing microbes.
