Therm-a-Rest Down Sleeping Bags Hyperion Sleeping Bag: 32F Down

Hyperion 32 Degree Down Sleeping Bag

New for 2019, the Hyperion 32 Degree Down Sleeping Bag is an ultralight backpacking option for those headed out into late spring or early fall conditions in uncertain weather. It features powerful 900-fill down insulation to keep you warm when the nights dip towards freezing, treated with Nikwax in order to retain heat-trapping loft if you encounter moisture on your trip. Cinch the draft collar down on colder nights for snuggle-worthy comfort, and rest easy knowing that a draft tube keeps cold air from sneaking through the zipper. The ergonomic mummy shape is built with mesh walls to maximize loft, and zoned insulation for maximum warmth with minimum weight. In addition to weighing in at merely a pound, the Hyperion packs down to little more than the size of your favorite 1 liter water bottle.
