Sierra Designs Nitro 20 800 Dridown Sleeping Bag
The Sierra Designs Nitro 20 800 DriDown (Regular) is a classic mummy bag and one of Sierra Designs' best-selling sleeping bags, built for backpackers who want low weight, comfort and simple, dependable tech. It is insulated with 800-fill-power, hydrophobic PFC-free DriDown and wrapped in ultralight 15-denier nylon ripstop to keep you warm even on damp nights.
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.
