NetPlus® is made from recycled fishing nets, creating a downproof yarn that also helps cut energy use during manufacturing. Compared to conventional nylon fabrics, NetPlus® reduces water use by up to 70% and overall energy consumption by up to 68%.


Pertex® YFuse® (YF) filaments have a uniquely engineered Y form, tightly interlocking to create highly stable yarn structures.
Whereas conventional, circular sectioned filaments lie loosely side by side, Y Fuse filaments interlock tightly in layers to create a unified yarn structure. Fabrics created using Y Fuse yarns have greatly enhanced downproof and water beading properties.
Our sleeping bags contain 100% Responsible Down Standard (RDS) down fill.
Certified to the Responsible Down Standard by TE-00118388.

Proud to own a Northwest legend
Great loft and warmth to weight ratio, silky feel, smart hood enclosure and zipper design. Exudes quality—worth every penny!

Swift 20 Reg
Excellent warmth, superior workmanship, fit is right on.

Great sleeping bag and customer service
The sleeping is great, and I also received a refund, as the company didn’t delivered my sleeping bag in the expected date.

Simply the best
What more is there to say other than the BEST sleeping bags. Best quality, fair price and made in USA. This my 4th Feathered Friends bag. My initial one, purchased over 40 years ago, is still great.

Very happy so far
I've not used the bag yet but the quality of construction shines through and I can't wait to use it. The hood is on the small side but i dont see that as an issue and worth the trade off for weight and compressibility. My head is still covered. I am glad I went with the larger diameter. I think the 60 inch would have been pretty cozy. I'm 6 2, 215 and wear a 44 reg. Hope that helps.
