Feathered Friends Snowy Owl EX -60 Sleeping Bag

The Feathered Friends Snowy Owl EX -60 is the most extreme bag in the lineup, built for polar expeditions with a -51°C limit rating. Its 1501 g of RDS-certified 900+ fill power goose down (US fill power standard) sits inside a Pertex Shield EX membrane; total weight of 2211 g and a 35 L packed volume make clear this is expedition gear, not backpacking gear. The manufacturer specifies a dual-zipper backup system for these conditions — a critical feature where a zipper failure could be life-threatening. Box-baffle construction with a differential cut and horizontal baffle orientation resists down settling, while the 3D anatomical hood combined with a draft collar and draft tube minimizes heat loss at the most exposed points. Regular size covers user heights up to 183 cm, and dimensions of 163/152/99 cm (shoulder/hip/foot box) leave room to sleep in bulky insulated layers. Both a stuff sack and storage sack are included, and it's also available in orange. Made in the USA.
