The Feathered Friends Petrel 10 UL Women's is an ultralight women's bag derived from the unisex Lark 10 UL, adapted to a women's build with extra fill concentrated around the feet and chest. With 565 g of 950+ fill power goose down and a total weight of 856 g, it carries a manufacturer limit rating of -12°C in the Short size for users up to 160 cm.
The Pertex Endurance UL 10D ripstop shell paired with a Flite 15D ripstop liner keeps weight low without sacrificing durability. A trapezoidal foot box adds room for the feet, and an adjustable contoured hood, draft collar and draft tube along the full-length two-way zipper limit heat loss. Unlike some other bags in the catalog, this one skips an internal pocket and foot-box venting — a stripped-down build focused purely on weight.
RDS certification confirms the down's ethical sourcing, and the bag ships with a stuff sack and storage sack. The Petrel 10 UL Women's targets women chasing a low base weight for cold three-season trips into light winter conditions, where every gram matters.
