Many sports equipment makers offer them for use when the weather is cold and Asics, Japan's biggest name in sports, has now introduced one for the official Tokyo 2020 Olympics merchandise catalog: the highly breathable Tokyo 2020 Olympics Asics Neck Gaiter is available in one size that fits all, and in black or gray color versions.
The Tokyo 2020 Olympics Asics Neck Gaiter is light, so you can even wear it even during the hot months. It's made of 100% polyester and has an antibacterial and odor-resistant coating that adds to your protection. And being part of the official Tokyo 2020 Olympics product lineup, it features the Games logo, the five rings emblem, and the legends for Tokyo 2020 as well as Asics, which is made of retroreflective paint to ensure you are visible when running at night!
