The Cooling series is perfect for hot seasons, designed to keep you cool and comfortable while wearing it. It utilizes eco-friendly materials and has been upgraded with a softer fabric feel. This crew neck underwear features partial breathable mesh, balancing contact cooling with breathability. The sleeves are made from smooth fabric that provides a cooling sensation, while the high thermal conductivity nylon material, crafted in a flat knitting structure, ensures lasting coolness. The front and back bodies are mesh for enhanced breathability and dryness. With excellent stretch, it smoothly follows dynamic movements. Treated with antibacterial and odor-resistant processing, it reduces discomfort from sweat odors. It offers a comfortable fit ideal for use as underwear while maintaining a relaxed silhouette with minimal constriction. The length is designed to stay secure and not expose the back even during movement. To lessen environmental impact, part of the material is made from recycled fibers.
