How to use: Put on the welding cap with the deep crown sitting just above your eyebrows. Adjust it to make sure the ear coverage is comfortable. You can extend the hidden flap inside the bill for extra neck protection when needed. Precautions: Don't expose the cap to extremely high temperatures or sharp objects that could damage the flame-resistant fabric. Maintenance advice: Machine wash the cap as needed. It can maintain its flame-resistant protection through 50 home washes. But avoid using harsh detergents that might reduce its performance.
