[Edaily Reporter KYUNG GYEYOUNG ] As a heatwave with temperatures exceeding 40 degrees continues across the country, consumption of cooling apparel is on the rise.

According to TOPTEN10, a manufacturing and retail (SPA) brand operated by ShinsungTongsang(005390), sales of TOPTEN10’s summer functional line, “COOL Air,” have increased. In particular, from July 27 to August 2, sales volume of “COOL Air Cotton”—a flagship product in the COOL Air line—rose by 64% and sales revenue by 67% compared to the same period last year.

TOPTEN attributes this to growing demand for products with cooling features—even for everyday wear such as commuting to work or spending time indoors—as the heatwave has persisted.

COOL Air is a line of functional products—including T-shirts, highly breathable items, tank tops, and undergarments such as bra camisoles—designed to provide comfort in hot weather through cooling and quick-drying features. COOL Air Cotton combines cotton fabric with a quick-drying function that wicks away sweat.

A Top Ten representative from Shinsung Trading stated, “Demand for cooling apparel, which began early due to the heat arriving sooner than usual, is expanding further amid the recent record-breaking heatwave.” They added, “As more consumers are seeking functional features like cooling and quick-drying even in everyday items such as T-shirts and innerwear, we will continue to deliver the value of ‘Goodwear’ through our Cool Air lineup, which is designed with a variety of wearing environments in mind.”
