When you’ve spent the better part of the day trekking through the wilderness, it’s important that you give your body some rest and get a good night’s sleep. In order to do that, you need to stay comfortable till sunup. It can be challenging to get the sleep you need if you’re not used to sleeping outside. That’s why you’ll want to make sure your Sleeping Bag isn’t just adequate but comfortable too. The Synthesis 20° Sleeping Bag from Sierra Designs is just the ticket to a cozy night at camp!

Sleep fortifies memory. While you're catching Zzz's, your brain is able to restore the part where it hangs onto memories—the hippocampus. The connections between brain cells in this area are strengthened during a good night of sleep. Keep all the great memories you're creating at summer camp locked in when you spend a cozy night in the Synthesis 20°.

From soft pongee fabric at the neck to SierraLoft™ synthetic insulation for all-over warmth, the Synthesis provides comfort the second you crawl inside with a super-silky feel, higher loft, fast decompression time, and incomparable warmth to weight ratio. This insulation is lighter, warmer, and more resistant to water as well as cold temps than most other synthetic insulations.

With a durable water repellent (DWR) coating on the shell, The Synthesis 20° keeps any rain from soaking in! Sierra Designs has implemented new technologies to make a DWR coating that creates both a breathable and effective product without the use of PFCs (man-made chemicals that are harmful to the earth).

In this "do-it-all" sleeping bag, get your temperature dialed in just how you like with features such as the patented self-sealing foot vent that delivers immediate ventilation at the toe as well as the cinching hood that traps heat in around your head. Its draft collar that runs alongside the zipper keeps undesirable cold spots from getting through and the dual, anti-snag zipper system makes adjustments easy in the middle of the night.

With strengthened memory, you’re sure to recall your best nights of sleep in the Synthesis 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.”
