Feathered Friends Lark 10 UL Sleeping Bag

The Feathered Friends Lark 10 UL is an ultralight bag pitched at cold three-season use through light winter trips. Filled with 568 g of 950+ fill power goose down, it reaches a manufacturer limit rating of -12°C at a total weight of 887 g — a notably low weight for the stated temperature range. The Pertex Endurance UL 10D nylon shell carries a DWR finish that beads off moisture without the added weight of a full waterproof membrane, while the Flite 15D ripstop liner keeps the interior weight down further. A trapezoidal foot box adds room for the feet, a draft collar and draft tube limit heat loss, and the full-length two-way zipper allows venting or opening flat as a quilt. The unisex Regular size fits up to 183 cm, ships with a stuff sack and storage sack, and is made in Seattle under RDS certification. The Lark 10 UL suits hikers chasing a low base weight who still want a genuine margin for cold nights, rather than a bag rated with little headroom.
