MOON-TECH® Short-Sleeve Shirt Blouson (collaboration with WWS)
A collaboration item with WWS, which created "workwear that looks like a suit" — a product that "changes the way clothes are" — and has sold over 250,000 units. This short-sleeved shirt blouson uses "MOON-TECH®", an advanced technological material equipped with 12 high-level functionalities, achieving both lightness and a structured feel. (The material of this product is knitted fabric.)
It features a box silhouette that doesn't pick up body lines, providing a relaxed fit.
While offering a comfortable amount of room, its exquisite silhouette is not too loose, creating a naturally polished impression just by putting it on.
The snap-button closure makes it easy to put on and take off, allowing you to casually wear it according to the temperature or occasion.
It also has pockets on both sides, offering storage capacity and practicality.
From business to holidays, commuting to travel.
This is the "just right" piece that combines light comfort with a polished look.
