Therm-a-Rest Hyperion Down Sleeping Bag
Built for fast-and-light mountain travel, this bag uses 900-fill Nikwax Hydrophobic down to achieve a 20°F rating at just 1 pound in Regular size. The down absorbs 90% less water and maintains loft 60 times longer than untreated fill, and box baffle construction maximizes loft while minimizing cold spots. The 10D nylon ripstop shell keeps weight minimal while the ultralight fit reduces excess space and bulk.
