If you have tried to wear a helmet in the past, either for costume or reenactment, you know that some are not so comfortable. They are designed to fit all sizes for the most part, unless you find one with an adjustable liner but even then, it is recommended to wear this Helmet Arming Cap underneath. Your head will sweat, so rather than soiling the liner of the helmet, this simple piece will keep your helmet clean. If the helmet doesn’t have a liner, the cap will help you get a more secure fit, so it is not moving around on you. It is made from cloth, and will fit all of our helmets here at Armor Venue. Please note that you must be at least 18 years of age to purchase this item.
