Birds chirping. Bugs buzzing. Leaves swishing…there’s no better feeling than waking up with the rest of the world in the great outdoors. You rub your eyes, stretch your arms, and indulge in a giant, satisfying yawn. You’re likely to be quite well-rested after a night spent in the Women’s Synthesis 20° Sleeping Bag. Once awake, you’re on your feet to roll up your sleeping bag and attach it to your backpack, ready for the camp adventures that lie ahead! 

SierraLoft synthetic insulation and lightweight, durable materials set apart premium sleeping bags like Sierra Designs’ from the rest. SierraLoft insulation is silky-soft. It offers high loft, quick expansion after-storage compression, and an excellent warmth to weight ratio too. It’s lighter, warmer, and more resistant to wet conditions and cold temperatures than other synthetic insulations.

Not long ago, in order to make outdoor gear effective as well as breathable, people used a water repellent with man-made chemicals called PFCs. They’ve since been discovered to be harmful to the environment. Sierra Designs has implemented new technologies to make an effective DWR coating that’s also breathable and doesn’t use PFCs. Stay dry and breathe easy in this Synthesis Sleeping Bag!

Between the self-sealing foot vent that provides ventilation at the toe and the cinching hood around your head that keeps heat trapped inside, you can keep your temperature rather finely tuned. With a draft collar along the zipper, this bag prevents uncomfortable cold spots from getting to you and dual, anti-snag zipper system that makes adjustments easy, even when you’re half-awake in the middle of the night! Stay cozy at summer camp in the Women's Synthesis 20° Sleeping Bag.

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.”
