BisonShield™

BisonShield™

Outerwear and accessories made with salvaged American Bison fiber

Introducing
The Bison Ultralight

Weighing in at under a pound, the Bison Ultralight has a brand new insulation we developed exclusively for a packable jacket. At 50% wool and 50% bison fiber, it’s warmer, lighter, entirely natural, and the batted insulation means you won’t be pulling feathers from your sleeves.

100% Natural Inner, 100% Recycled Outer

While the natural insulation keeps you toasty, the Ultralight’s  recycled ripstop shell (ripstop, which was developed for the military, gives the jacket extra durability) is finished with a PFC-free water resistant coating, which keeps you dry without the chemicals.

The Perfect
Airplane Pillow

Quicker than you can count to thirty, the Ultralight can be packed into its own interior pocket to transform into a travel-friendly airplane pillow.

A Salvaged
Performance Fiber

When we realized the untapped potential of bison fiber, a material largely considered a waste product by the ranching industry, we developed a supply chain to salvage it before it could be discarded. No bison have been harmed for the purpose of their fiber. We’re simply stepping in to divert a precious, existing resource that’s been grossly underutilized.

Benefits of Bison

The American Bison’s shaggy coat consists of a layer of hollow, compact and resilient hairs that allow them to keep warm and dry in some of the harshest climates. And it packs more than incredible warmth; bison fiber is also temperature-regulating, hypoallergenic, lightweight and flexible.

BisonShield™ Yarn

Through many iterations of bison products, we’ve landed on the minimum amount of bison fiber needed in a product for its powerful effects to really shine: 5%. BisonShield™ yarn is comprised of 10% bison fiber blended with recycled polyester, wool and nylon, allowing for socks, beanies and other cold-weather accessories that regulate temperature, wick moisture, stay warm even when wet, and fit like a glove.

Socks We Can’t
Keep in Stock

The first product of our BisonShield™ yarn, the Ultimate Bison Sock, sold out within weeks—and has sold out every year since. It’s a testament to the benefits that bison fiber provides (and it’s also just the coziest sock ever).
