Experience one of the most comfortable backpacking sleeping bags available. The Sierra Designs Cloud 800F 35° Down Sleeping Bag builds on the award-winning Backcountry Bed design and was named Outside Magazine’s “Best Sleeping Bag for Backpacking.” Its innovative zipperless design with an integrated comforter creates a natural sleeping experience while reducing weight and bulk.

Constructed with durable 15D nylon ripstop fabric and filled with premium 800-fill power DriDown insulation, the Cloud delivers exceptional warmth, compressibility, and lightweight performance for backpacking and alpine adventures. The self-sealing foot vent allows quick temperature control without letting cold air in, while the integrated pad sleeve keeps your sleeping pad securely in place as you move during the night.

The result is an ultra-comfortable, lightweight mummy sleeping bag designed for backpackers who want warmth, freedom of movement, and efficient packability on the trail.

1 lb 7 oz (654g–660g) for the regular size. The long version weighs about 1 lb 9 oz (710g)
