Smart and strong, the Bellamy doesn't just put Jack Frost on ice--it shuts him down completely. The Bellamy is our first line of defense against Old Man Winter and the first line of offense when taking the elements head-on. Made with Polartec® Power Grid® fabric, the soft, textured interior helps regulate our temp by trapping the right amount of heat without bulk, all while still delivering wicking and overall breathability. All that makes for one hard-working, hard-playing, long-lasting gold medal fleece. Warms even when wet. By Patagonia. XS(2), S(4-6), M(8-10), L(12-14), XL(16).
