Get those splendid nights of sleep in between adventures with The Boswell 20° Sleeping Bag from Sierra Designs.

Preference to sleep on your stomach or your side is no problem in The Boswell Sleeping Bag thanks to its oversized, rectangular shape. A lot like food and water, a good night’s sleep is essential. Our immune systems need time to recharge! When we’re asleep, it gives our bodies a chance to recoup so it can fight off incoming toxins in the coming day. That's how the Boswell Sleeping Bag helps your camper stay healthy and ready for the day!

Super comfy, soft pongee fabric at the neck transitions to SierraLoft™ synthetic insulation for all-over warmth the second you crawl inside. Sierra Designs’ Synthetic Insulation delivers a super-silky feel, higher loft, faster decompression time, and a much higher ratio of warmth to weight. This makes it lighter, warmer, as well as more resistant to moisture and cold than most other synthetic insulations.

With a durable water repellent (DWR) coating on the shell, The Boswell 20° keeps a damp night chill away. While Sierra Designs has utilized new technologies to make their DWR coating free of man-made chemicals called PFCs, these nasty little things were used in nearly all DWR coated products before it was discovered how harmful they were to the earth.

On top of a sizable body, fantastic insulation, and environmentally-friendly water repellency, Sierra Designs gave this sleeping bag compulsory features such as the dual-sliding and anti-snag zipper that gives you custom ventilation, an adjustable hood for extra warmth, and internal stash pocket for convenience when it’s time to pack up and hit the trail! Enjoy feeling refreshed when you set out for the day and…

Think Outside.


The Sierra Designs Story

Founded in 1965 by Bob Swanson and George Marks, Sierra Designs was built on the basis of providing excellent gear to adventurous spirits from all walks, whether you’re an expert thru-hiker or a first-year summer camper. Bob and George first met as co-workers at The Ski Hut, an outdoor equipment retailer in Berkeley, where the two often dreamed of owning their own business. This outdoorsy duo got their wish one day when a wealthy benefactor gave them the money they needed to seed their new company: Sierra Designs. The Sierra Designs family is still composed of outdoorsy folks who all happily to do their part to protect our environment. For them, it means making products with as little impact to the environment as possible such as using recycled material and creating an environmentally-friendly water repellent that’s PFC-Free. As they like to say, “Think outside, because happiness is found in the adventure.”
