900+ Goose Down

We source our premium goose down from Eastern Europe. Our suppliers use time-honored practices such as hand gathering from small family farms, coupled with modern processing facilities featuring sustainable water and energy systems. The combination of high quality raw goose down and superior processing result in down clusters of unrivaled quality. All of the goose down we use is certified to the Responsible Down Standard (RDS).

900+ Muscovy Down

Ultrasonic Muscovy Down™comes from Muscovy ducks, a breed known for producing large and resilient down clusters that are closer in structure to Eider down than to traditionally sourced duck down. Our Muscovy down has undergone a patented ultrasonic washing process to ensure ultra-clean, odor-free, high-lofting down clusters. Ultrasonic Muscovy down is RDS and Bluesign certified.

Because Ultrasonic Muscovy is much less expensive than comparable fill power goose down, using Ultrasonic Muscovy allows us to offer a lower price point option for some products, without sacrificing quality standards.

What Is The Difference?

Besides the fact that goose down comes from geese and Muscovy down comes from ducks, the main difference is price. Market factors including availability, geolocation, and a stigma against traditional duck down make Muscovy down less expensive than goose down.

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.

Pertex® YFuse® Shell Fabric

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 YF-series of sleeping bags, whether 900+ Goose down or 900+ Muscovy down, contain 100% Responsible Down Standard (RDS) down fill.

Certified to the Responsible Down Standard by TE-99977174.
