A 3mm, extra close mesh structure, which secures both short and long hair effectively, whilst maintaining airflow. Featuring an excellent quality, single elastic headband, for those who experience pressure sensitivity, or, wear hard hats, bump caps or other rigid headwear. Manufactured with polypropylene yarn for high moisture transportation and wicking properties; ultimately, keeping operatives cooler and more comfortable and less prone to touching and adjusting headwear.
