Sierra Designs Nitro 20 Classic Mummy Sleeping Bag - Regular

Alter your tastes, tap into lightweight, mummy-style comfort.

Simple construction and a classic mummy bag shape are the hallmarks of one of our best-selling sleeping bags for backpackers who put a premium on low weight, incredible comfort and straightforward tech. The Nitro 20 sleeping bag is designed with durable nylon ripstop and insulated with 800-fill, hydrophobic DriDown to keep you toasty warm, even on damp nights. A draft collar seals in the heat when moving around, and sidewall baffles prevent the down from shifting and causing cold spots, but our patented self-sealing foot vent provides relief to hot sleepers without the need to kick off the covers. Top it off with an anti-snag zipper to eliminate sleepy struggles and take greater comfort with this intuitive mummy bag.

Our Mission

We believe in creating equipment that empowers people to get outdoors with products that are accessible, thoughtful and beautiful.

Born in California and Bred on the Trail.

Bob Swanson and George Marks founded Sierra Designs in 1965 on the premise that all people deserve to have good gear for exploring the outdoors regardless of their background or experience level. That meant creating products that were trail tested, inspired by any adventure and trouble-free.

While some things have changed in the last 50 years, our mission hasn't. Today Sierra Designs continues to be a place where you can find happy dogs, new ideas, and always reliable camping gear. We find inspiration in mountains, deserts, and beaches. We find inspiration in the every day outside our office and the trails headed straight into the heart of the Rocky Mountains. We find inspiration in any adventure, big or small. We are people who Think Outside, because happiness is found in the adventure.
