The Norrona men’s TROLLVEGGEN DOWN850 jacket is a lighter, warmer, and more durable insulator made for the demanding pursuits of mountaineers. This ultra-warm jacket delivers excellent warmth thanks to its 850 fill power padding of European Standard, RDS Certified down. Down850 means the filling is 850 to 900 cu in/oz along with 93-to-96 percentage of down clusters. A sturdy and finely woven Pertex Quantum face fabric offers weather-resistance against harsh alpine conditions. This TROLLVEGGEN DOWN850 has a more fitted design, improving its range of motion and volume size. A storm hood that’s freeride helmet compatible can guard against falling snow. Practical hand warming pockets provide storage for avalanche gear.
