Overview

Built-In Technology

3DeFX+ by TORAY
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.

Stunner Stretch Fabric by TORAY
Down insulation requires an added down-proof layer, or the down clusters and feathers can poke through the fabric. These added layers are noisy, bulky, and heavy. Stunner Stretch fabric is spec’d with a heat treatment process that creates a barrier down cannot penetrate. This fabric stretches as you move and offers the lightweight, quiet, and comfort hunters demand.

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.

The ULTRA name in a KUIU product signifies a priority for streamlined design and ultralight weight. Combining industry leading fabric and hardware with Toray 3DeFX+® insulation has opened the door to a category of highly breathable insulation pieces for active use, that are perfect for high-output cold weather mountain hunting applications.

3DeFX+ synthetic insulation is the first of its kind to incorporate continuous fiber technology. The long spiral strands of fill are loftier and warmer than any other synthetic insulation on the market, and don’t require fabric coating to keep the insulation from migrating through the fabric.

Kenai ULTRA vest features insulation mapping, which offers higher insulation in the front for warmth, with lighter insulation on the back for added breathability and better temperature control while wearing a pack.

The 30D Stunner Stretch® nylon face fabric is strong, light, and dead quiet. Uncoated fabric and insulation mapping allow us to make a vest that breathes at an exponentially higher rate, keeping the user dryer, warmer, and more comfortable during long climbs and extremely active use.

FEATURES
  • Insulated mid to outer layer
  • High warmth-to-weight ratio
  • 2-way stretch fabric
  • Quick drying
  • Wind resistant
  • DWR to repel water
  • Zippered hand pockets
  • Zippered chest pocket
  • Adjustable hem
  • YKK Zippers
  • NYLON 66 cording
  • DURAFLEX hardware
