The Extreme Cold Weather Iceline sleeping bag is engineered for mountaineers tackling the most frigid climates. With a remarkable temperature rating of -22°F, this sleeping bag ensures a good night’s sleep even at high altitudes. The bag features a lightweight yet durable GORE-TEX® INFINIUM™ 10-denier outer shell, which provides exceptional breathability while protecting against snow and condensation.

The expedition fit, enhanced by the EXL® system, offers increased loft and thermal efficiency, allowing you to wear additional layers comfortably inside the bag.
Designed with vertically aligned V-baffles and ground-level side seams, this cold weather sleeping bag maximizes thermal efficiency. The anatomically shaped hood and footbox utilize BullsEye™ technology for optimal down control, ensuring warmth where you need it most. Plus, the innovative Lode Lock™ closure system provides quick access while keeping your essentials safe and dry.
