The Cooling series is perfect for the hot season, designed to keep you cool and comfortable. Made with eco-friendly materials, the fabric has been updated for a softer feel. This mock neck underwear covers the neck from sunlight and is crafted with smooth fabric for a cooling effect. With high heat conductivity nylon made into a flat knit structure, it offers sustained coolness. Its excellent stretch allows for smooth movement during dynamic activities. Treated with antimicrobial and odor-resistant processing, it reduces discomfort from sweat odors. While providing a fit that is easy to wear as underwear, it features a relaxed silhouette with minimal constriction. The longer length is designed to prevent exposure of the back when moving. Additionally, to reduce environmental impact, some materials incorporate recycled yarn.

No sunburn

I purchased gray because it seems to have better UV protection than white. It feels light to wear, so I can endure the scorching heat even with long sleeves. It feels cool when sweat dries.

Comfortable to wear

I bought it because I wanted to wear it while playing tennis. It's not too tight, has a nice separation from the skin, and is very comfortable to wear.
Since the school is on break until the end of August, I plan to wear it starting September.
I'm looking forward to it already.
