Extreme protection for the coldest frontiers!
From frozen alpine camps to remote Arctic crossings, the Polar Overbag is an essential addition for winter adventurers who demand uncompromising warmth and protection. Designed to shift the dew point outside your primary sleeping bag, it ensures your insulation remains dry, even during multi-day expeditions in severe cold.
Lightweight yet incredibly effective, this overbag features Climashield® Apex insulation (3 oz/yd² front and bottom) and a waterproof Pertex® Quantum Pro shell (0.85 oz/yd², 10-denier ripstop nylon). Its ergonomically contoured hood reduces condensation from breathing, while dual front YKK® zippers (5 mm, full length, 4 sliders) provide hassle-free access and ventilation. A dedicated structural element in the lower part of the hood can be folded into the main body of the sleeping bag to protect the mouth area—preventing moisture buildup and keeping your down dry.
By adding up to 18°F (10°C) to your existing sleep system, it transforms a standard winter sleep setup into an expedition-ready shelter. Its spacious design fits sleeping bags with up to 53 oz of down (1500 g).
Compact and packable, the Polar Overbag is an essential piece of gear for mountaineers, cold-weather trekkers, and expedition teams alike. When temperatures plummet and conditions turn unforgiving, you can count on it to deliver the extra warmth and protection you need to push forward with confidence.
