Shivering is overrated. At belays and bivies, the high-loft Micro Puff Vest offers cold-weather sanity through ultralight, compressible core warmth. Its durable, supremely efficient synthetic insulation (100-g PrimaLoft One) traps heat even when wet, and the 100% recycled polyester shell with a Deluge DWR (durable water repellent) finish blocks wind and sheds snow. The front zipper is treated with a Deluge DWR and backed by a low-bulk wind flap. Pockets: two handwarmers and one interior zippered chest that doubles as a stuff sack (with a carabiner clip-in loop). Drawcord hem. |
