What Our Gearhead(R) Experts Are Saying: "This vest is a great layering piece when I want warmth without bulk in the arms. The Warm3 fleece traps heat really well but still feels light, so it's perfect under a shell or just over a baselayer in cold weather. I've used it for climbing approaches and around camp, and it's equally at home in town with its retro look."
