The Swallow YF 20 is their flagship three-season mummy bag, filled with 900+ fill power ethically sourced goose down -- the highest loft-to-weight ratio commercially available. The Pertex Quantum shell fabric is ultralight at 20 denier while providing sufficient wind and moisture resistance for most backcountry conditions.
At 1 pound 14 ounces for a regular size, the Swallow competes with bags costing $200 more from competitors using equivalent fill. Feathered Friends offers a lifetime warranty against defects in materials and workmanship, and their Seattle workshop performs repairs, re-baffling, and down replenishment on bags of any age.
This repair program is the critical BIFL differentiator: a well-maintained down bag can perform for 20 to 30 years, and Feathered Friends actively enables that lifespan. At roughly $450, the cost-per-night over a 20-year career of 50 nights per year works out to 45 cents per night of warm sleep.
The mummy cut is snug by modern standards, and side sleepers may prefer a wider quilt design. But for weight-conscious mountaineers and thru-hikers who need reliable warmth in a compact package, Feathered Friends delivers Seattle craftsmanship backed by a warranty that means what it says.
