Cuddling up to your tentmate may keep you warm when temps drop below freezing, but when your climbing partner indulges a little too hard in the freeze-dried macaroni your Therm-a-Rest Centari Sleeping Bag is there to swoop in and save the day. Stuffed with eraLoft insulation, this synthetic bag is lightweight, compressible, and won't leave you soaked when your tent buddy tracks a little snow in. Therm-a-Rest strategically places higher concentrations on insulation where you need it most, to enhance warmth and cut unnecessary weight--because let's face it, if you're camping in the snow chances are you've got quite enough weight to carry as it is.
