NAVY BLUE LIGHTWEIGHT NECK WARMER The C-LAB neck warmer is made of lightweight tubular fabric (seamless), preventing friction and irritation. Its material effectively protects you from the cold, even on the windiest days, while remaining breathable. As all cyclists know, you can use it as a helmet liner, balaclava, neck gaiter, or a beanie for jogging. Measuring 45cm in circumference by 45cm in length, it takes up minimal space and easily tucks away into a small pocket.
