Comfort conditioning technology for a smooth, quick-drying feel. AIRism is UNIQLO’s high‑performance comfort technology designed to reduce heat, humidity, and discomfort caused by sweat. Made with ultra‑fine fibers thinner than a human hair, AIRism lifts sweat away from the skin, spreads moisture quickly, and dries fast to keep you feeling fresh. Originally developed as functional innerwear, AIRism has evolved into everyday clothing that delivers smooth, lightweight comfort all year round.

When you wear clothing, heat and moisture can build up between your skin and the fabric, creating discomfort. AIRism is engineered to manage this microclimate by lifting sweat through capillary action and releasing moisture quickly into the air. The result is fabric that stays dry, smooth, and comfortable, even in hot or humid conditions.
