Product Overview

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 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.

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.

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.
