Sierra Designs Nitro 0 800 Dridown Sleeping Bag - Long

The Sierra Designs Nitro 0 800 DriDown (Long) is a classic mummy bag built for backpackers who want low weight and dependable warmth in colder conditions. Insulated with 800-fill-power hydrophobic PFC-free DriDown and wrapped in ultralight 15-denier nylon ripstop, this 0F bag keeps you warm on cold nights, and the Long version fits taller campers up to 6ft 6in (198cm).

A draft collar seals in heat, while 5-inch baffle spacing and sidewall baffles stop the down shifting and forming cold spots. The patented self-sealing foot vent gives warmer sleepers relief without kicking off the covers, and an anti-snag zipper makes getting in and out easy.
