Fabric Definition:
Bison fiber is a rare, incredibly soft, and exceptionally warm natural protein fiber harvested from the downy undercoat of the North American Bison, prized for its superior insulation, lightweight feel, and sustainable, regenerative harvesting.
Composition:
100% Keratin (Protein) – extremely fine, hollow core, with a natural crimp; typically 16-22 microns, lanolin-free
Texture:
Unbelievably soft, downy, light, and airy; similar to cashmere but with a drier, warmer hand; subtle matte luster, non-itchy
Stretch Level:
Low (Natural crimp provides gentle elasticity; blends with nylon or silk add structural stretch)
Fabric Construction:
Woven (e.g., Bison Suiting, Blends) or Knitted (e.g., Jersey, Rib, Cable Knit)
GSM Range:
150-550 GSM (Light for base layers, medium for sweaters, heavy for outerwear and wraps)
Breathability:
Excellent – Highly breathable, excellent moisture-wicking and temperature regulation
Moisture Management:
Excellent – Hollow fibers absorb and release moisture efficiently, keeping skin dry in cold conditions
Durability:
High – Surprisingly strong and resilient for a fine fiber; resists pilling and matting with proper care
Thermal Properties:
Exceptional – Superior warmth-to-weight ratio; 2-3 times warmer than sheep wool, exceptional for extreme cold
Key Usage Areas:
Ultra-Luxury Knitwear (Sweaters, Cardigans), High-End Accessories (Scarves, Hats, Gloves), Shawls, Stoles, Baby Blankets, Premium Outerwear, Cold-Weather Base Layers
High-end hospitality (boutique hotels), private aviation, elite expedition gear, luxury equestrian apparel
