Primeflex Nylon

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 Nylon 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.

KUIU Torain® 3-Layer Fabric

Busting through brush will shred delicate rain gear. Torain 3-Layer fabric features a durable stretch nylon face fabric and offers great tear strength. It’s crafted with an Entrant® microporous hydrophobic membrane that breathes well during all levels of activity. Torain adds a revolutionary new seam tape that gives enhanced hydrolysis resistance for improved garment longevity.

K-DWR® (KUIU DURABLE WATER REPELLENT)

Once a fabric is soaked, insulation and breathability are compromised. K-DWR treatments bead and resist water, keeping it from penetrating the outer layer. This increased breathability and performance allow waterproof membranes to evaporate your sweat while blocking out moisture. K-DWR also enhances dry-time and protects from light rain or dew-soaked vegetation on non-waterproof products.
