The award-winning Duvet. Recognized for exceptional, thoughtful design.

The Most Innovative Luxury Bedding

Hyperdown debuted in Japan in 2016, where it is currently sold in 150 retailers and online at, and has quickly risen in popularity thanks to its light weight and warmth. Now available in the U.S. you can say goodbye to dirty down, heavy comforters, and electric blankets. “We strive to create technologically advanced products for the most comfortable sleep environment possible,” said airweave Founder and CEO, Motokuni Takaoka. "The Hyperdown Duvet is the winter companion to our line of mattresses."

Different At Its Core

Extra Warm

Extra warmth is created through hygroscopic heat build up, the ability to convert moisture into heat, thanks to our innovative Hyperdown fill. When combined with an outer shell designed to provide the highest level of insulation, this is the perfect duvet for cooler temperatures.

Next Benefit

Humidity Control

Most duvets trap heat and moisture leaving you tossing and turning uncomfortably due to a high level of humidity. Hyperdown is able to take moisture and convert it into heat leaving you comfortably warm and sound asleep.

Next Benefit


While natural down can attract dirt, microbes, and cause allergies, Hyperdown is antimicrobial, hypoallergenic, and even controls odors. Wash easily by hand or dry clean.

Next Benefit


We support cruelty-free bedding and, as a company built on innovation, are proud to develop an alternative that is superior to natural down.

The Hyperdown Duvet

Hyperdown (Inner)

Hyperdown is our proprietary premium fill consisting of fine synthetic fibers that replicate the feel of down. Thanks to the Hyperdown's molecular makeup, the down alternative converts moisture into heat and is ultra lightweight. Added benefits include its antimicrobial, hypoallergenic, and odor-resistant properties.

Outer Shell

A luxurious 449 thread count of cotton sateen, expertly finished so that it conforms to your body, stays in place while sleeping, and provides maximum heat retention. While baffle box or sewn through are the typical duvet constructions, we use a special ring-quilting that allows for less sewing but still holds the Hyperdown in place.



The warm air generated by Hyperdown circulates throughout your sleep environment thanks to airfiber®'s breathable design. This controls your core body temperature to help you stay in the deepest of slumber and never feeling like you're too hot or too cold.
