This light duty layering piece might surprise most users by its ability to be used for just about any sport in almost any temperature range. It can be used for cold weather layering, or just to keep the chills at bay for early morning summer hikes. The 4 way stretch makes it great for sports that require a big range of motion, like climbing, and the interior fleece lining makes it comfortable for sitting and doing nothing. It’s a must have for most active people.
