Planning on spending extended periods in icy cold weather' Better also plan on having the Norrona Trollveggen 750 Women's Down Jacket with you. It's Norrona's warmest, with ethically raised and harvested 750 fill European down packed inside of a recycled downproof polyester shell and topped off with strategically placed PrimaLoft Gold synthetic insulation to resist moisture and packing out. The wire brimmed storm hood and hem seal up with single hand drawcords to keep you draft free when you're belaying, hanging out at basecamp, or bivying for the night. The soft chin guard prevents irritation, which is the last thing you need when you're in a rugged spot. When you're not wearing it, pack the Trollveggen safely into its own pocket for storage and hit the road to your next adventure.
