DO YOUR RESEARCH: QUIXDOWN INSULATION

What is it?

KUIU’s Quixdown® is a premium goose down insulation that goes through a proprietary cleaning process, and then treated with a durable water repellent (DWR) to each plume of down, making it nearly impervious to water. 

Why use it in our gear?

It’s the highest quality down available, resistant to water, and will maintain insulating loft even if it gets wet. Down has the highest warmth-to-weight ratio of any insulation, now with Quixdown you can tackle the toughest and wettest mountain hunts without the fear of your down wetting out.

What makes it the best?

The down is refined and processed by Kawada Feather in Japan. Their proprietary techniques perfect the down to a remarkable high-loft 850+ fill power and 95:5 down-to-feather ratio. Once cleaned, the down is treated with Toray’s DWR, making it resist wetout far better than our competitor’s water-resistant down.
