Like your own bed in the backcountry! Our Doublewide Series eliminates the need to zip two bags together so theres nothing keeping you apart from your cuddle bug in your tent, van, or wherever you need a super comfy bed. The much improved Sentinel 30 is insulated with 650 fill DownTek ; a water-repellent down insulation that repels water while maintaining insulating properties and loft for 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 quilted soft polyester shell fabric on top and cozy polyester taffeta 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.
