Thank you for viewing. I used it once for a few hours and it has been home cleaned. It's a thick fleece, so it's warm. This is a high-performance neck gaiter perfect for winter sports such as winter mountaineering and skiing. It uses a medium-thick material with excellent stretch in the main fabric. It also has excellent sweat absorption, providing a comfortable fit. The part that covers the mouth and nose uses Clima-Prene® with a pile lining on the back, which not only shuts out the wind but also makes it difficult for the fabric itself to retain water, making it less likely to freeze. It can be used with a helmet or hat, and can be worn even with the mouth exposed.
