Simple made better.
A new alternative to down.
We took on the challenge of reproducing the warmth of down without the weight to create PUFFTECH, high-performance insulation synthetic fibers. Working hand-in-hand with Toray Industries, UNIQLO spent about 10 years developing PUFFTECH, a fiberfill that mimics the structure of down. This fiberfill contains plenty of air to achieve unprecedented levels of lightness and warmth. This next-generation outerwear meets the needs of a new era.

Warmth derived from air.
How do we achieve the lightness and warmth of insulated down? After 10 years of joint development with Toray Industries, we created PUFFTECH – high-performance insulation, made of ultra-fine fibers, ⅕ the width of a strand of human hair. Each fiber is hollow and has a spring-like 3D shape, allowing for air to insulate and create warmth.
*The fineness of some fibers, considering hair size as 0.08mm for comparison with polyester fibers.
Moisture-resistant warmth.
Generally, when natural down gets wet, it loses volume and warmth and takes longer to dry.
PUFFTECH is resistant to moisture absorption, so it can maintain sufficient warmth even in environments with humidity of 90% or more. Thanks to 3D padding, PUFFTECH expands more easily compared to conventional granular padding, so it can more easily return to its original volume even when wet.
Made to keep you comfortable in any weather.
Beyond lightness and warmth, it’s built to handle unexpected rain.
A seamless, dual-layer nylon construction keeps wind and water out.
Reliable performance, in every detail.

Washable. Made to be worn all winter.
Lightweight and warm. And washable. Making outerwear for children means development has to have a fundamentally different purpose. The Ball Padding we developed with Toray is lightweight and structured to hold plenty of warm air, while also being easy to care for. Play hard, get dirty, toss it in the washer. We've added many other touches. The fastener is easy to handle while wearing gloves, and we've designed the collar with a chin guard to keep the fastener from touching the chin. There's also a name tag on the back side. We've considered every detail to keep kids warm.

Warmth you can pack along.
Now with a packable pouch that neatly stores the parka, it’s easier to carry and use on the go, adapting comfortably when temperatures change unexpectedly throughout the day. By switching the outer fabric from polyester to nylon and reducing the denier from 35 to 25, the jacket is now approximately 100g lighter, with a noticeably softer feel—while maintaining its warmth and functionality and fitting more naturally into everyday life. A reliable companion that makes winter days more comfortable.
