No Side Effects

If you're sick of choosing between sleeping uncomfortably on your back all night and waking up multiple times because your hip is numb, then the Big Agnes Men's Sidewinder Camp 35 Sleeping Bag is for you. Made by side-sleepers for side-sleepers, the Sidewinder features a centered zipper, making it easy to get into and out of the bag. Plus, this design keeps the zipper out from under you as you roll from side to side throughout the night. To keep you cozy and tucked in all night, Big Agnes threw in extra padding in the hips and foot box to keep numb legs at bay. Inside, you'll find trusty warmth in the form of FireLine™ ECO Synthetic Insulation, made from 100% post-consumer recycled polyester, as well as a cozy polyester taffeta lining to help you rest easy after a long day spent in the great outdoors.
