The Super Down ULTRA Jacket is our lightest, warmest, most packable insulation yet, in an athletic, collared jacket design.

• Weight: 6.4 oz (total garment weight)
• 100% Nylon, 26 g/m² 12D ripstop fabric
• Down & fabric treated for water resistance
• 1.8 oz of Premium 850+FP Polish Goose Down (min 90% down)

Product Overview

INCREDIBLY LIGHTWEIGHT, PACKABLE, AND WARM

In the Super Down ULTRA system, we have cut the fabric weight down by 40% compared to the original Super Down. The fabric features a new Toray finishing process which employs heat processing to slightly melt the fabric into a down-proof structure. This process reduces the need for coatings, allowing for an even lighter fabric.

Featuring Toray's DWR-treated QUIXDOWN, KUIU's down insulation systems keep their loft even when wet. 850+ down fill power means that 1 oz of down takes up at least 850 cubic inches of volume, making it the loftiest (and therefore warmest) on the market. In the Super Down ULTRA system, the new double-baffle structure keeps down migration to a minimum, preventing cold patches.

In the Super Down ULTRA Jacket, we've brought the hand pockets up and away from the hem, allowing for easy access when wearing with your pack. The left hand pocket doubles as a stuff sack, allowing for easy packing.

Technology

Quixdown® by Toray

Waterproof Warmth 

Down has the highest warmth-to-weight ratio of any insulation material. The only drawback is that once wet, down stops being effective. Not anymore. Through nanotechnology, Toray Industries has created a water repellent finish for down feathers that makes each down cluster essentially waterproof. Quixdown® stays dry to keep you warmer with less weight and bulk.

Stunner® Stretch Fabric by Toray

Lightweight, Stretchable Comfort

Toray develops a new fabric technology and KUIU brings it to Mountain Hunters first! Ultralight, down-proof Stunner Stretch fabrics stretch as you move and put a layer of luxurious comfort between you and the warm softness of KUIU’s premium Polish down. And, of course, Stunner Stretch minimizes bulk and weight.

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.
