Sierra Designs Sleeping Bags

Sierra Designs sleeping bags are engineered to handle anything Mother Nature can dish out. Our selection of 3-season sleeping bags, 4-season sleeping bags, ultralight sleeping bags, and bivys will make your next adventure under the stars a dream. Sierra Designs was the first outfitter to design sleeping bags for women specifically, narrower at the shoulders, wider at the hips and sized for height.

Check out our game-changing DriDown™ sleeping bags. DriDown™ represents the evolution of down insulation. We treat regular down with a molecular level polymer to create a hydrophobic finish on each individual down plume. This finish allows DriDown™ to stay dry longer, loft better, and dry faster than untreated down, keeping you warmer in any environment.
