SKY BLUE NECK WARMER The C-LAB neck warmer is made from lightweight, tubular (seamless) fabric. It prevents skin chafing and the resulting irritation caused by seams. Despite its lightweight material, it effectively protects you from the cold even on the windiest days, while remaining breathable. As all cyclists know, you can use the neck warmer as a helmet liner, balaclava, neck gaiter, bandana, or beanie for jogging or cross-country skiing. Measuring 45cm in circumference by 45cm in length, it takes up minimal space and fits easily into a small pocket.
