You must wear an approved mask that will protect your face. That is supplied with all our packages. Then you need full coverage, such as long sleeves and long pants. The younger crowd seems to prefer hooded sweatshirts, as then even the back of the head and neck is covered.
Layering on clothes is a great idea, and since GatSplat fields are indoor, heated and air conditioned, you can wear any protection you want, summer or winter, and be comfortable.
We do have an entire protection set you can rent for just $10 per person. That includes coveralls, a chest and back protector, and a set of armored gloves. When the day is over, strip off the coveralls and leave the washing to us.
