Description As seen in Outside Magazine, our Convict Half Zip Pullover Hoodie is made with Polartec Power Wool. We designed this piece as a lightweight and highly breathable mid-layer for backcountry travel. The grid construction of the fabric allows for incredible breathability that regulates the start-stop cycle in the backcountry better than anything else we've tried. The air pockets provide warmth when you're idle but breathe well when you're going up. And all of this performance weighs about as much as a standard t-shirt and compresses well so you can squeeze it in a small or full pack if you do take it off. Don't take our word for it though - see an in-depth review from Outdoor Gear Lab.
