Hyperion 20F/-6C Sleeping Bag

Slide the featherlight Therm-a-Rest Hyperion Sleeping Bag: 20 Degree Down into your trusty backpacking pack before a long through 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 wont ruin your trip. This bag also features an ergonomic shape and longer zipper that makes it far more comfortable than some competitors bag in the ultralight category. The Therm-a-Rest Hyperion 20 Degree sleeping bag comes in different sizes to accommodate different heights. Small fits 5’1” to 5’6”, Medium fits 5’ 7” to 6’, and Large fits 6’ 1’ to 6’ 6”.

One of the lightest pieces in its class, the Hyperion sets a new standard for high-performance outdoor equipment.
Unrivaled Packability:
Lightweight materials and precise design allow for a smaller packed size than ever before.
Box Baffled Construction:
To maximize thermal efficiency in key areas, we use mesh box baffles to boost loft and eliminate cold spots at the seams of the sleeping bag or quilt.
Comfort Fit:
Ergonomic shape and longer zipper provide a more human-friendly fit than other ultralight bags.
SynergyLink™ Connectors:
These removable straps integrate your mattress and sleeping bag to minimize heat loss and keep you secure through the night.
Zoned Insulation
Maximizes warmth and saves weight by intentionally placing fill where you need it most, 70% on the top and sides with 30% on the back.
Responsible Down Standard Certified:
All of our down is certified to the Responsible Down Standard so that you can sleep easy knowing that the waterfowl have been treated humanely.
