Product Details    

Style: S1112

Built for comfort, the Sea to Summit Ascent AC1 Long Sleeping Bag is your three-season solution for comfortable nights spent out of doors. It's rated at 25°F, allowing you to enjoy camping later and earlier in the year than lighter bags. And the long design, along with built-in Draft Tubes at the zipper and neck, help taller users comfortably seal their heat in to keep cozy all night long. It's useful when the weather isn't quite so crisp too, thanks to a separate foot zipper that lets you vent some heat on warmer nights, and the full-length side zipper that lets it open up and be used as a quilt.
