Like your own bed in the backcountry! Our Doublewide Series eliminates the need to zip two bags together so there’s nothing keeping you apart from your cuddle bug in your tent, van, or wherever you need a super comfy bed. The much improved Big Creek 30 is insulated with FireLine ECO synthetic; a 100% post-consumer recyled insulation with lofty and compressible fibers that provide a cozy, warm sleep experience. The Flex Pad Sleeve on the bottom makes connecting two pads or stretching around a doublewide pad easier and fast than ever while still allowing the soft shell fabric on top andcozy polyester lining inside to drape like the comforter on your bed. So snuggle in for the night, this might be your best night's rest under the stars.
