Ridiculously lightweight warmth. The Hyperion -6C packs down to the size of a loaf of bread, weighs the same as a big can of soup and keeps you warm when the temp dips below freezing. The secret sauce is the premium 900-fill-power down insulation that has great compressibility and provides exceptional warmth at a light weight, combined with mesh box baffled construction that maximizes loft and minimizes cold spots.
- Gossamer-thin 10-denier ripstop nylon shell and lining save weight and bulk. DWR-treated shell repels water moisture and condensation.
- Down has a Nikwax hydrophobic treatment to dry faster, maintain loft better and retain less moisture than traditional down.
- Down is certified to the Responsible Down Standard for animal welfare.
- Zoned insulation provides insulation where it's needed – on top. Because sleeping pads provide additional insulation, there is less on the bottom of this bag.
- Reflective ThermaCapture™ lining seals in heat to provide additional warmth without adding grams.
- 2 Removable SynergyLink™ connectors hold your mattress in place under the bag for better thermal efficiency and comfort.
- Snag-free zipper with full-length draft tube keeps cold air from sneaking in.
- Ergonomic shape provides a less restrictive fit than other ultralight bags.
- Includes both a stuff sack and a storage sack.

EN Comfort Temperature Rating
This sleeping bag has been tested to the EN standard in a certified lab. This controlled test measures thermal value using a heated mannequin (wearing a base layer and a hat) placed on a 1-inch pad. The Comfort Rating is the lowest temperature at which the bag will keep the average woman (or "cold sleeper") comfortable.
EN Limit Temperature Rating
