Faster Compression Recovery

Muscovy down clusters are exceptionally resilient, meaning they "spring back" quickly for greater loft capabilities and faster compression recovery.

Bigger Plumes

The more mature the duck, the bigger the plume! Due to the longer breeding period of Muscovy ducks, they produce plumes that are as large or larger than those of geese.

Stable Clusters

Muscovy down has an inherent "clinginess" comparable to Eider duck down, meaning each plume has the tendency to "grab on" to another, which creates more stability within each baffle and reduces shifting.

Free-Range Birds

Muscovy down is a byproduct of the food industry, but unlike battery-farmed ducks, Muscovy birds are ethically-raised in open, free-range environments with access to water.

    Additive-Free, Achieving Highest Fill Power (950FP+!)

    Untreated down clusters preserve their full loft, avoiding the performance loss common with treated downs. This results in the highest lofting Muscovy down ever—providing maximum warmth at minimum weight.

    Uses Less Water & Energy

    Because the patented Ultrasonic Washing Technology cleans down more effectively, the process uses 20% less water and energy through fewer rinse cycles, resulting in a high performance down that is not only cleaner, but more environmentally friendly as well.
