Product Overview


The KUIU Active Insulated Jacket features the same Toray 3DeFX+ stretch insulation as the Kenai Insulated Jacket. The continuous fiber structure of 3DeFX+ eliminates the need for fabric coating, so that the softest, quietest fabrics can be used. Coating-free fabric is also extremely breathable, allowing for comfort and regulated temperature during active use. With its streamlined silhouette, we've been able to cut out several ounces, making it our lightest synthetic insulation jacket.

• Stretch binding finished cuffs
• Open hand pockets
• Chin guard for added comfort
• YKK zipper


3DeFX+® by Toray

Warmth and Flexibility Intersect

Toray’s 3DeFX+® combines insulation made from coil-shaped fibers and stretch fabrics to provide unmatched warmth and freedom of movement. Its continuous fiber technology is loftier and warmer than other synthetic insulation options, and perfect when the need for extreme warmth and flexibility intersect.

Toray’s Kudos® XR DWR

Kudos® XR DWR (Durable Water-Repellent)

Kudos XR DWR performs better and lasts significantly longer than conventional DWR. DWR is critical for waterproof breathable face fabric. If DWR fails the face fabric “wets out” causing condensation build up on the inside of the garment.
