Product Overview


The Super Down PRO Pants are for the coldest hunts. They're sized to fit over your boots, base and mid-layers. They're ideal when temperatures plunge and low-level activity—like long glassing sessions or sitting in a stand. They're insulated with 3.2 oz of 850+FP Quixdown (Twice the down as ULTRA), making it KUIU’s warmest down pant.

Our Super Down products outperform the competition. We start with the best Polish goose down, which is cleaned, refined and processed by Kawada Feather in Meiwa, Japan. Their proprietary techniques perfect the down to a remarkable 850+ fill power and 95:5 down-to-feather ratio. Once cleaned, we treat the down with TORAY’s DWR, so each individual cluster is impervious to water; keeping its insulating loft even when wet.

The outer 30D Stunner Stretch nylon fabric is the perfect combination of performance and stretch. It's heat-treated to keep the down from migrating through the fabric, eliminating the need for noisy down-proof coatings. The fabric is also treated with TORAY K-DWR to repel light rain and snow.

The pants feature reinforced 70D x 80D paneling along the seat, knee and cuff for added protection. They compress and self-stow inside the left pocket for compact storage. They're so lightweight, you won’t regret having them in your pack.

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.

K DWR® (KUIU Durable Water Resistant)

K-DWR is the first line of defense for keeping you dry. It keeps water from penetrating the outer-layer fabric, which promotes breathability and performance.
