Made of high-density nylon ripstop used for parachutes and tents, it is lightweight with moderate breathability and water repellency. The soft fabric is woven in a “W” shape with large ventilation holes in the back to handle the humidity of early summer. Piping on the lining tightens the rough impression, while the color expresses Whimsy's character. The generous sleeves are a distinctive feature, and the ribbed hemline when zipped is also a good feature.
