Feathered Friends Raven 10 UL Sleeping Bag

The Feathered Friends Raven 10 UL is the ultralight version of the Raven mummy bag, filled with 632 g of RDS-certified 950+ fill power goose down under a Pertex Quantum Pro 7D recycled nylon ripstop shell. At a -12°C (10°F) limit rating and just 950 g total weight in Regular size, it's among the lightest four-season bags in the lineup — the trade-off being a DWR-treated shell rather than a waterproof membrane, so rain protection is limited. Continuous baffle construction with a differential cut keeps the down evenly distributed over repeated use, and a full-length, two-way zipper on the left side lets you regulate temperature without fully opening the bag. A fitted, contoured hood together with a draft collar and draft tube handle insulation at the most heat-sensitive points. The Flyte liner fabric is recycled, and the whole construction is PFC-free. Both a stuff sack and a storage sack are included. Shoulder and hip measurements aren't specified for this model.
