This is a tubular neck gaiter made of stretchy, thin material with the ITU triathlon logo. When used as a mask to cover the mouth and nose, it shrinks to fit the shape of the face, so it won't slip during sports. The quick-drying material also eliminates moisture build-up inside the warmer caused by breathing. It can be used all season long: as a sweatband or wristband in the summer, and as a cap or balaclava for cold protection in the winter. It is highly elastic and can be used in various ways. Size: 25.5cm x 49cm (flat)
