Teton Bros. short-sleeved T-shirt. Size (measured flat): Width: Approximately 53cm Short sleeve from the Dry Action series. The fabric used for the PPP series was changed from 17SS. The main feature of Dry Action is its lightweight material, weighing only 90g per square meter, with excellent breathability and a comfortable feel due to its grid structure that prevents stickiness. This material is treated with Dry Action, the world's highest standard of water-repellent processing, and is used in the PPP series. It has water repellency that can be called waterproof and ultra-fast drying properties, and prevents overheating due to the synergistic effect with excellent breathability. In addition, the extremely thin grid shape allows it to function as a base layer, keeping the body surface dry at all times. [Regarding washing water-repellent fabric] You can use regular laundry detergent, but avoid using fabric softener as it can reduce the function. If you accidentally use fabric softener, rinse it with water or lukewarm water for about 10 minutes. Also, avoid using bleach as it degrades the water-repellent function. *Please purchase with understanding that this is a used item. After washing, it has been stored at home (no smoking, no pets).
