Big AgnesHitchens UL Sleeping Bag: 20 Degree Down

Ultralight warmth for minimalist explorers.

From trekking across the Swiss Alps to backpacking across Maine's highlands, the Big Agnes Hitchens UL 20 Degree Sleeping Bag retains fiery warmth without holding you back with unnecessary weight. This ultralight sleeping bag is rated to 20F for optimal warmth when overnights dip below freezing. The bag's nylon ripstop shell is both lightweight and extremely durable. It features a DWR coating that repels morning condensation from seeping through and compromising the down insulation inside.

850-fill DownTek insulation provides an exceptional warmth-to-weight ratio, satisfying the needs of lightweight backcountry enthusiasts. This down insulation features a hydrophobic treatment that repels moisture in wet environments. Ultimately, this means you'll stay pleasantly warm when drizzly conditions and high humidity levels threaten to leave you shivering-cold. Contoured baffles retain uniform heat distribution throughout the night. For greater warmth in windy conditions, the oversized draft collar locks in precious body heat from escaping.

  • Familiarity: I've used it several times

I used this bag while backpacking in the Cirque of the Towers. The temperature got down to around 34 degrees and this bag kept me completely warm. It was light enough to pack and comfortable for sleeping. My only gripe was it didn't compress as much as I would have liked, I used my own compression sack and still couldn't get it down to a super small size, it was still small enough to fit into my sleeping bag compartment in my pack though. I would highly recommend this bag for anyone wanting a lightweight but warm bag for Spring or Fall backpacking.
