Lap after lap of deep powder with a pack on keeps the shoulders and arms working, and the UYN x PM Ski Team Top is a fitted base layer top that adds targeted compression and muscle support under a jacket. The top is one piece of a three-piece technical base layer system, the first collaboration between Perfect Moment and UYN, and it combines Italian innovation with Perfect Moment's sporty look. What Our Gearhead(R) Experts Are Saying:"Over a week of ski trip days where I changed my layering every morning, this was the one piece I never swapped out, because the breathable fabric never left me feeling clammy once I started working hard. The fitted cut lets my arms swing freely under a jacket, so no seam tugged when I reached for a pole plant."
