Reviews
Functional T-shirt
It has become increasingly hot every year, and I was interested in functional T-shirts rather than just regular ones, so I purchased this. It has a smooth texture and I can feel the deodorizing effect.

Savior for Sweaty People
I was worried that my body odor would become stronger due to excessive sweating while working. This Polartec Delta gradually dries to prevent sweat chilling, and it even has deodorizing properties. It's not all about merino wool, but for those who sweat too much and are troubled by the characteristic sulfur smell of merino, I recommend this.

POLARTEC Delta
POLARTEC Delta is a high-performance material developed by the American company Polartec, featuring moisture-wicking cooling technology designed for comfort in hot environments and during exercise. This material is designed to support the body's natural cooling system, sweating, efficiently absorbing sweat while moderately vaporizing it to provide a cooling effect. Unlike traditional quick-dry materials, it provides a continuous cooling function by gradually drying, rather than completely evaporating sweat. It also boasts high breathability due to its special knitting structure. Furthermore, it has antibacterial processing to suppress unpleasant odors from sweat and can be used comfortably while maintaining cleanliness.
