Product Stories
Gorgeous colors born from fine yarn.
Extra fine merino wool, with its incredibly thin fibers, produces a certain sheen and a vivid color palette. UNIQLO's aim has been to create beautiful colors consistently by dyeing the wool when it's raw, instead of after it’s been spun into yarn.


Easy-care, 100% wool.
Wool is a surprisingly dainty, natural material with a pleasing texture, which can sometimes require extra care. But at UNIQLO, we've worked out several ways to overcome that. With a special non-shrink treatment, this sweater becomes machine washable and prevents pilling, while retaining the material's elegant feel.


Still beautiful, 15 washes later.
Natural materials can be tough to care for. That's why we're updating the conventional wisdom. We've given the wool special, non shrink and anti-pilling treatments while retaining the delicate texture. We tried machine washing it 15 times*, and you can see the result in the photo. There's no noticeable pilling or fuzz It looks so good, you can hardly tell which one has been washed 15 times.
*Testing used a Type C (pulsator) washing machine at the Kaken Test Center following the JIS L1930 testing method.
*Ironed after washing.

Roger Federer's favorite sweater for every season.
Merino sweater is Uniqlo Global Brand Ambassador Roger Federer's favorite for many reasons. For one, it can be used for a variety of occasions during any season. They’re also lightweight, wrinkle-resistant, and machine-washable, perfect for Roger’s travels around the world. "I used to dress it up with a collared shirt underneath, but lately I've been wearing it with a T-shirt and jeans for a casual look, or under an evening jacket with dress pants". he says.


Fully enhancing color and luster.
Using extra fine merino wool, known for its incredibly thin fibers, allows us to achieve vibrant color and elegant luster. To maximize these characteristics, we dye the wool before it’s spun, ensuring even color distribution over time. The wool is then transformed into beautiful thread through a process called "drawing", which aligns the separated fibers. While the knitting is done by machine, the linking of each part is meticulously crafted by skilled artisans. Finally, we apply a washable treatment to ensure the knitwear remains beautiful and easy to care for. The higher the quality of the knitwear, the more you’ll want to enjoy its comfortable fit every day, and our comprehensive production process embodies this ideal.
