The women's Sidney SL 25 sleeping bag features a first of its kind customizable fit system with exterior hook and loop closures, so you make the call on a comfortable length and width depending on how you sleep or what the temperature is. This bag also features the patent-pending REM Pad Sleeve™; clip the stuff sack to the back of the bag and slide your pad in to ensure you won't roll off during the night.  With soft, technical fabrics, an anti-snag zipper draft tube, and 650 fill power DownTek™ insulation, this bag's versatility is ready to tackle peaks, canyons, and all the roads less traveled. Rest easy, mama.
