The present invention relates to a protective mask adapted to be worn by a person engaging in the game of paintball. The mask has a main body to cover the front, sides, mouth and ears of a user's face. It also has a removable flexible transparent lens that locks into a rigid support frame formed in the mask. The mask also has a strap to securely support the mask on a wearer's head, and a removable face engaging element provided to accommodate a face of the wearer. This face engagement element evenly engages around the wearer's face in a cushioned manner because its face engagement portion is made of foam that engages the user's face along the entire perimeter of the face engagement element. The face engagement element is securely locked onto the mask by locking clips that fit into openings on both sides of the face engagement element.
