_______________________
A collaboration item with "mastermind JAPAN", a Japanese street casual brand that focuses on "MADE IN JAPAN", incorporating Japanese materials, traditional techniques, and the latest technology into real clothing and disseminating it to the world.
Following the T-shirts and long-sleeved T-shirts that have been developed so far, this collaboration marks the debut of a SWEATSHIRT.
This special piece is based on the same body as the "Airfreak® Ultra-light Sweat Crewneck" launched last year, incorporating the worldview of mastermind JAPAN.
The brand's iconic skull is printed on the back, and the "MASTERMIND" and "MOONRAKERS" logos are placed on the front hem.
You'll barely feel its weight.
Your body will feel light, as if freed from gravity.
Our goal was to create the world's lightest SWEATSHIRT.
It offers a comfortable feel as if wrapped in warm air and high heat retention that utilizes the insulating properties of air. In addition to being machine washable, no-iron, and quick-drying, it is also resistant to shrinking and pilling, combining ease of handling with durability.
Lighter.
Warmer.
Easier to handle.
This is a new SWEATSHIRT that combines mastermind JAPAN's design with MOONRAKERS' material technology.
【Product Features】
■ Product Style
A "just right" SWEATSHIRT based on a basic crewneck design.
With a moderately thick material, it can be worn throughout the long season from autumn to mid-winter and early spring. It's a versatile piece that can be incorporated into a wide range of styles, both as an inner layer and as outerwear.
■ Lightweight and Insulating
Uses Toray's advanced technology material "KARUISHI®" as the base fabric.
By applying MOONRAKERS' unique processing to a special knitting technique that creates a long napped surface on the back, a large amount of air (dead air) is retained inside the material. This achieves astonishing lightness and high heat retention.
