Skins Snow Top - Long-Sleeve
Here's what other sites are saying:
Compression isn't a myth; just ask your local hospital how long they have relied on the blood-circulating abilities of compression. The SKINS Snow Top uses compression to push blood to the heart more efficiently while you're out testing your physical abilities in the backcountry. Designed with gradient compression and muscle support for your chest, back, and arms, the Snow Top not only improves circulation (which allows you to go harder and longer), but it also acts as a baselayer to wick moisture so you stay warm and dry, even in the most challenging conditions.
