The Doublewide Series eliminates the need to zip two bags together so there’s no barrier between you and your camp cuddle bug. The Sleepy Bear 35° is insulated with Fireline™ Core Synthetic Insulation, a multi-denier, hollow core insulation that provides loft, structure, warmth and durability. The Flex Pad Sleeve on the bottom makes connecting two pads or stretching around a doublewide pad easier and faster than ever. You’ll sleep like a bear with the soft shell fabric on top and cozy polyester lining on the inside, that drape just like the comforter on your bed at home. So snuggle up for the night in your tent, van, or wherever you need a super comfy backcountry doublewide bed.
