The Cooling series is perfect for hot seasons, designed to keep you cool and comfortable while wearing it. This updated version features eco-friendly materials with a softer fabric feel. The crew neck underwear incorporates partially ventilated mesh, ensuring both contact cooling and breathability. The sleeves are made from a smooth fabric that provides a refreshing feel thanks to high thermal conductivity nylon blended into a flat knit structure, sustaining a cooling effect. The front and back body feature a mesh design for added breathability and dryness. With excellent stretch, it smoothly adapts to dynamic movements. The antimicrobial and odor-resistant treatment reduces discomfort from sweat odors. It offers a fit that is easy to wear as underwear while providing a relaxed silhouette with minimal constriction. The length is designed longer to reduce exposure of the back when moving. To minimize environmental impact, some of the materials used contain recycled fibers.

Cool
For summer mountain climbing, a short-sleeved T-shirt is essential. It's strangely cool when you sweat. Contrary to what you might think, the fabric doesn't feel sticky against your skin, so there's no discomfort. Black

Perfect for summer
For someone who gets hot easily like me, this is an absolute necessity. Even when I sweat, it quickly feels cool when I go to a cooler place.
