Product Stories
Gorgeous colors born from fine yarn.
With its thin fibers, Extra Fine Merino wool has a shiny surface and produces vivid colors. To create consistently elegant colors, we dye the wool when it's raw instead of after it's spun into yarn.


100% easy care, 100% wool.
Wool can require extra care, but we've developed several methods to overcome this. With a special non-shrinking treatment, this sweater is machine washable while retaining the elegant feel of wool. We also apply a treatment to suppress pilling and twisting, producing a 100% wool sweater that will look great for a long time.


Retains its beauty, wash after wash.
Natural materials can be challenging to care for. That's why we're updating the conventional wisdom. We've given the wool unique non-shrink and anti-pilling treatments while retaining the delicate texture. We tested this sweater*, and you can see the result in the photo—there's no noticeable pilling or fuzz.
*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 year-round sweater.
The Merino Sweater is UNIQLO Global Brand Ambassador Roger Federer's favorite for many reasons. It's perfect for various occasions in any season, such as staying warm from fall to spring and taking it with him on evening walks in the summer. Another reason is that it's lightweight, wrinkle-resistant, and machine-washable for his travels worldwide. "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.


Enhancing the fine color and luster.
Only by using Extra Fine Merino, which has extremely thin fibers, were we able to achieve excellent color and elegant luster. Dyeing happens at the pre-spun stage. The wool is dyed evenly over time and transformed into a beautiful thread through a process called "drawing," which makes the separated fibers uniform. A machine does the knitting, but artisans hand link each part. Then, by applying washable processing, it creates a fabric that's elegant and easy to care for.
