The Ortovox Downwool 180 Hooded Jacket blends 70 percent down with 30 percent wool, so the insulation keeps lofting and holding warmth even when conditions turn damp. A windproof, water-resistant outer made from recycled polyamide protects the fill from light rain, and the whole jacket packs into its own stowaway bag for easy carry under a pack or in a pocket. A 2-in-1 adjustable hood and protective collar add coverage without adding bulk, so the jacket works as a standalone layer or under a shell through every season. What Our Gearhead(R) Experts Are Saying:"I caught light rain on a climb where a straight down jacket would have gone flat and cold on me, and this one kept lofting and holding heat the whole way. That's the difference wool in the fill actually makes."
