40x More Water-Resistant

Alton Sleeping Bags and Camping Quilts are filled with DownTek™ 850FP goose down feathers. Up to 40x more water-resistant than untreated down, DownTek™ is proven to stay drier and warmer for up to 80% longer than the competition. Goose down sleeping bags are light, easy to compress, breathable and durable. They provide superior insulation, higher loft, and better warmth-to-weight ratio compared to synthetic fill, making them ideal for cold weather ultralight hiking expeditions. And with a water-proof, wind-resistant Ripstop Nylon outer shell for added protection, this Sleeping Bag will keep you warm and dry, even in the most extreme conditions with available temperature ratings of 0 degrees, -5 degrees and -10 degrees.
