Hummingbird YF 20/30 Sleeping Bag
When every gram counts and warmth can’t be compromised the Hummingbird is the versatile bag of choice. With the slimmest cut in our lineup, the Hummingbird leaves no room to spare; perfect for going fast and light.
Available in 20 Degree and 30 Degree options.
Hummingbird too tight for comfort? Check out the Swallow or Swift for the same great features with a little more room.
Our YF line of sleeping bags feature a lightweight, 100% nylon Pertex® Quantum® shell that uses yarns with unique Y-shaped filaments to create a fabric with increased downproofing and water beading properties, even after years of use and washing.
YF: YFuse. Pertex Quantum® 20 denier mini-ripstop fabric
Details
