Summer heat is relentless — especially when you're packed into a crowded train, rushing through your commute, or sitting through a long school day with no relief in sight.
Shirt Cool Strong (シャツクール 冷感ストロング) by Kobayashi Pharmaceutical is Japan's trusted answer to sweltering heat. One quick spray on your clothing and you'll feel the difference the moment you start to sweat. The active l-Menthol formula works with your body — every time perspiration touches the treated fabric, it triggers a powerful, lasting cooling sensation that keeps you comfortable for hours.
It's not just cooling. Shirt Cool Strong also deodorizes sweat odors and kills germs on your clothing, so you stay fresh from morning to night. The light, refreshing mint scent completes the experience without being overpowering.
Made in Japan. Used daily by millions of commuters, students, and professionals across Asia. Now available worldwide through Shirt Ice.
