For only 15 bucks, you can get yourself a GEN X Global paintball mask. Although the Gen X mask is inexpensive, it will still keep you safe and protected on the paintball field. Since the mask is such a reasonable price, the lenses for it are very reasonably priced as well. The Gen X Global Lens and mask are both ASTM approved and will get you in the game for a great price. To change out your mask lens for only 5 bucks is unheard of. The Gen X Global lenses only come in one style and one color which is the single pane clear lens, but for such a low price... who really cares.
If you have a Gen X Global mask, you should pick up a spare lens for it today so you wont ever have to sit out a game on the sidelines.
