Beauty sleep is important, even in the backcountry camping fact 6: bears won't eat you unless you've got bags under your eyes, so make sure you wake up well rested every morning by spending chilly nights in the Big Agnes Pristine 17 Degree Synthetic Women's Sleeping Bag. The Pristine, which weighs in right around three pounds, uses Bluesign approved Pinneco Core insulation to provide a top shelf combination of light weight, warmth, and breathability that's perfect for lightweight backpacking trips when nights are expected to drop into the teens. The CoreScreen design repels external water, too, so tent condensation won't turn you into a soggy popsicle. The Pristine's mummy shape and 360 degree Insotect Tubic baffle construction pack lots of insulating power and form fitting comfort into a small, easily packable bag, but the Pristine still features a no draft collar and zipper to keep warm air in and cold air out, and a contoured hood that seals around your head to keep you comfy in sub freezing temps. Since waking up with frost bitten toes can ruin your trip, Big Agnes stuffed the foot box with extra insulation, and built the Pristine with vertical baffles to keep the insulation where you need it most, helping you to sleep so soundly that the bears will almost certainly leave you alone.
