Our Technology

KUIU was founded on the principle

of bringing new innovative fabric technologies to the hunting industry to solve the problems that are faced in the field. This notion built a movement of passionate outdoorsmen who demand the highest performance from their equipment. The technologies below are the outcome of our relentless pursuit of innovation.

3DeFX+®

Drastic stop-and-go activity levels can cause a buildup of sweat, leaving you chilled when you’re stationary. To mitigate this issue, breathable 3DeFX+ active insulation evaporates moisture while you’re active. Its continuous insulating fibers eliminate the ends that poke through the fabric, allowing us to spec a quieter uncoated fabric, giving you the ideal insulating layer for active hunts.

QuixDown®

Traditional down had never been a viable option for mountain hunting, considering it loses all insulating properties when subjected to moisture. Not anymore. We treat each down cluster with DWR, so its impervious to moisture. We use the finest Polish goose down and perfect it with proprietary techniques to a remarkable 850+ fill power and 95:5 down to feather ratio.

Primeflex® Stretch Fabric

Fabrics that get their stretch from as much as 10% elastane, spandex, and Lycra® materials are heavy, slow to dry, and don’t last. Primeflex fabrics solve the problem of restrictive clothing by utilizing a patented spiral yarn that allows the fabric to stretch and recover without using water-absorbing spandex. Primeflex fabrics are quick dry and offer durability, comfort, and stretch without the weight.

Dot Air®

While hunting in hot conditions: durability, concealment, and protection from the sun can’t be sacrificed to keep cool. To solve this challenge, the Tiburon series uses a durable and breathable Dot Air® fabric that features UPF 40+ sun protection rating, and Makpsec® odor reducing technology. Tiburon keeps you comfortable, concealed, and protected in the hottest conditions.

Nuyarn®

As good as traditional merino was, Nuyarn is better. Classic yarns twist fibers together for strength, which leaves ends poking out that can cause irritation. Nuyarn takes the twist out, and instead, lays fibers along the same orientation, so fabrics feel less prickly and more comfortable. By eliminating the spun yarn, we get merino wool that has more loft, stretch, and durability.

Dermizax® NX

Active backpack hunts require packable raingear that breathes well and stretches with your every move. Dermizax® NX membrane is completely windproof and waterproof and offers 200% four-way stretch comfort while eliminating bulk and weight. Its smooth texture and lightweight configuration make Dermizax® NX up to four times more breathable than other waterproof fabrics, and the perfect choice for super-lightweight, waterproof, breathable gear.

Wind Resistant Fleece

Blocking wind by adding extra layers adds unwanted weight and bulk. Our Wind Resistant Fleece Technology takes a new approach to blocking wind and eliminates the windproof membrane by utilizing a unique bonding technique between the face fabric and fleece backer. This trims weight and resists wind while also having exceptional breathability, stretch and soft next-to-skin feel.

Karuishi Fleece

Warmth doesn’t come at the price of added weight. Unlike ordinary fleece, Karuishi Fleece uses a 2-layer knit structure with a brushed fleece interior for more loft and better insulating properties, while the exterior is tightly woven for higher abrasion resistance. Features quiet ultra-fine polyester fibers for an ultra-soft feel with a hydrophobic nature that wicks moisture away from your skin.
