Norrona Trollveggan Warm2 Stretch Pullover
Here's what other sites are saying:
Norrona created the Men's Trollvegen Warm2 Stretch Pullover Top for backcountry adventures where extreme conditions demand peak performance from gear. Warm2's tight weave means wind stays out and warmth stays in, and added durability is a plus as well. A high level of flex and stretch allows you a full and natural range of motion.
