Therm-a-Rest Down Sleeping Bags Hyperion Sleeping Bag: 20F Down

Why We Like The Hyperion Sleeping Bag

Slide the featherlight Therm-a-Rest Hyperion Sleeping Bag into your trusty backpacking pack before a long thru-hike. The lightweight and packable construction of this sleeping bag will ensure there is plenty of room in your pack for other necessities. The 900-fill Nikwax Hydrophobic Down makes this warmth and packability possible by trapping your body heat in strategic areas and compressing to an impressively small size. As an added bonus the Nikwax treatment means the down can handle moisture without losing its loft so that a surprise rainstorm won’t ruin your trip. This bag also features an ergonomic shape and longer zipper that makes it far more comfortable than some competitor’s bags in the ultralight category.
