Feathered Friends Widgeon EX -10 Sleeping Bag

The Widgeon EX -10 sits at the cold end of Feathered Friends' range, a four-season expedition mummy bag rated to -10°F/-23°C and built around 848 g of 900 fill-power RDS-certified goose down for a total weight of 1483 g. That is a serious amount of down and fabric, reflected in a warmth-to-weight figure well below the brand's three-season bags – this bag trades grams for margin against genuine winter cold. The Pertex Shield EX shell (15D/40D ripstop) is a fully waterproof-breathable membrane rather than the DWR-treated or water-resistant fabrics used elsewhere in the lineup, useful in wet snow or condensation-heavy winter tents. Continuous horizontal baffles with a differential cut let the down loft fully, and a full-length two-way zipper, draft collar, draft tube and fitted hood seal the system. An internal pocket keeps small items close. Made in the USA, this is expedition gear for alpine climbers and winter mountaineers, not backpackers optimizing base weight – at nearly 1.5 kg it is one of the heaviest bags in the catalog, built for reliability rather than a small pack size.
