Using this headcover is a breeze. Just attach the press - fit seal to your helmet. It works with most helmets, especially Lincoln Electric ones and many of the competitors' models. When using it, make sure the seal is firmly attached to get the best protection from sunlight, spatter, sparks, and UV light. For maintenance, you can gently hand - wash it with mild detergent in cool water. Avoid using harsh chemicals or machine - drying as it may damage the 100% FR Cotton material and the Kevlar stitching. After washing, let it air - dry. If you notice any tears or damage, it's best to replace the headcover to ensure continued protection.
