Stretch and puff merge to make this insulated, packable jacket worth far more than its weight in warmth.
Layer up and warm up. The men's Burton [ak] Baker Stretch Insulated Jacket uses high-loft down to keep you warm and lightweight stretch fabric means ease of mobility. You get valuable warmth for layering that packs into a pocket. Wear it under your shell, wear it in on its own. It's a do-it-all midlayer for backcountry missions and storm days alike.
