Side sleeping is the most common sleeping position for adults. Research shows that around 54% of us roll onto our sides when we want to get some kip, whether that's in a comfy bed at home or inside a toasty sleeping bag in the wilderness.
With so many people sleeping on their sides, it's a surprise that there aren't more sleeping bags like this one. The Big Agnes Sidewinder Camp 35 features a cocoon-style fit that hugs the contours of your body when you roll onto your side, and it's now available for just $100.73 in men's sizes and $118.73 in women's sizes at REI.
