Simple, made better.
A new alternative to down.
We took on the challenge of reproducing the warmth of down without the feathers to create PUFFERTECH: high-performance insulation from synthetic fibres. Working with Toray Industries, UNIQLO spent about 10 years developing PUFFERTECH, which mimics the structure of down in its ability to trap air to achieve unprecedented levels of lightness and warmth. This next-generation outerwear meets the needs of a new era.

Air, the secret to warmth.
How do we achieve the lightness and warmth of down, without the feathers? After 10 years of joint development with Toray Industries, we created PUFFERTECH – high-performance insulation made from ultra-fine fibres. Each fibre is hollow and has a spring-like 3D shape, trapping air and warmth.
*The fineness of some fibers, considering hair size as 0.08mm for comparison with polyester fibers.
Moisture-resistant warmth.
When down jackets get wet, they can lose volume and warmth and take a long time to dry. PUFFERTECH is resistant to moisture absorption, so it can maintain sufficient warmth even in environments with humidity of 90% or more. Thanks to its 3D structure, PUFFERTECH easily returns to its original volume, even when wet.
Made to keep you comfortable in any weather.
Beyond lightness and warmth, PUFFERTECH is built to handle unexpected rain thanks to a seamless, dual-layer, water-repellent nylon fabric.

Washable kids' clothing for winter.
Making outerwear for children meant we worked with Toray to create lightweight insulation that holds plenty of warm air, while also being easy to care for. We also made sure the zip was easy to use while wearing gloves, and added a chin guard and a name tag.

Warmth that travels.
Now with a packable storage pouch, it’s easier to carry PUFFERTECH on the go. We made the jacket approximately 100g lighter, with a noticeably softer feel—while maintaining its warmth and functionality.
