This is a hard core bag that provides ultimate warmth for high altitudes or winter camping – with minimal increase in weight and compressed size. The outer shell is constructed from a double layer of water repellent nylon, while the inner lining is 100% polyester for soft comfort. An extra pound of 700+ down filling ensures total warmth throughout the night. The bag features a 5½” x 8” zippered pocket at the chest for keeping keys and wallet close and safe. Compression sack included.
About Down Fill Ratings: The quality of down runs on a scale from 500 to 900, higher is better. We use high quality 700+ fill and adjust the amount of down in the bag to increase warmth rating.
