The Egret UL 20 is Feathered Friends' women's-specific mummy bag, cut shorter and narrower than the unisex line (fits users up to 160 cm) with extra down in the footbox and chest, where women tend to feel cold first. It's filled with 463 g of 950+ fill-power, RDS-certified goose down, weighs 723 g total, and carries a manufacturer limit rating of -7°C (20°F).
The Pertex Quantum Pro 7D×30D ripstop shell paired with a Flyte 10D liner and a reinforced Pertex Diamond Fuse 15D footbox keeps weight down without sacrificing durability. An adjustable, fitted hood, a draft collar, and a zipper draft tube all cut heat loss, and the bag ships with both a stuff sack and a storage sack.
With a warmth-to-weight ratio above 9.5 and a sub-750 g weight, the Egret UL 20 sits comfortably among ultralight bags suited to thru-hiking and serious base-weight-focused setups, though its -7°C limit rating puts it more in shoulder-season territory than deep winter.
