Many are deeply concerned as the Korea Meteorological Administration forecasts this summer to be hotter than usual. The concern primarily stems from sweat odor, a common summer nuisance. In response, the outdoor industry has introduced advanced cooling T-shirts that not only feature cooling functions but also effectively combat sweat odor, targeting consumers stressed by sweat smell.

Various outdoor brands such as Merrell, K2, Wide Angle, and Black Yak have differentiated themselves by offering products that not only provide a cool wearing experience but also combat unpleasant sweat odor with everything from deodorants essential for underarm care, to powders made from grinding jade, eucalyptus extract, chitosan, and green tea natural ingredients.

A Merrell representative stated, "Many are concerned about sweating just by standing due to the forecast of an unusually hot summer. Hence, the outdoor industry is showcasing products that not only provide excellent cooling effects but also effectively care for odors, allowing for a more comfortable summer free from the worries of sweat and sweat odor."
