Too many alpine shiver-fests can leave you mumbling incoherently and sporting a thousand-yard stare, but 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 Deluge® DWR (durable water repellent) 100% recycled polyester shell blocks wind and sheds snow. Front zipper is treated with 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. Recyclable through the Common Threads Recycling Program.
