Western Mountaineering AlpinLite Sleeping Bag - Wide Fit to -7°C

The Western Mountaineering AlpinLite sleeping bag gives you UltraLite performance with more room to move. It takes everything that makes the UltraLite a benchmark 3-season bag and adds a wider, more spacious cut, rated to -7°C.

With 14cm (5.5") of loft from 850+ fill power goose down, the AlpinLite keeps you warm across spring, summer and autumn and ready for cooler nights, and the 180cm length weighs just 880g. Continuous baffles let you shift the down for colder nights or balance it out in milder conditions, and an insulated draft tube and collar seal in warmth. The 12D ExtremeLite ripstop nylon shell is ultralight, breathable and durable for its class, and the wide mummy cut adds shoulder and hip room with space for light layering. Choose the AlpinLite over a narrow mummy bag when you want lightweight efficiency without feeling restricted.
