Colombia Neck Gaiter - Cool Type This neck gaiter can be used for activities such as mountain climbing. In addition to preventing heat, it also protects against UV rays and sunburn with UPF50. Material: 100% Polyester I purchased this two years ago but never used it, so it has been stored at home. The backing card has some scratches, but the main body is in good condition. Please feel free to ask if you have any questions. Thank you.
