ZAMST COOL SHADER Vest Material: Polyester/Polyurethane Used a few times, but I think there are no noticeable scratches or stains. I am selling it because I have another one. - Cools the body with a product that is -15℃ cooler than skin temperature. Simply wet it with water, wring it out, and shake it to activate the cooling effect through evaporative cooling. - Becomes cold every time you shake it. Long-lasting cooling. Even if you feel the coldness has weakened, it becomes cold again with each shake. *The effect decreases as the water content of the product decreases. In that case, wet it with water again. - UV protection: Cuts over 97% of UV rays and can also be used for sun protection. Recommended for cooling during rounds, as well as for heat and UV protection during sports観戦 and golf観戦.
