Invert paintball masks come in several types and colors for every budget. The Avatar masks have soft molded plastic and a dual density foam for full comfort. The Rapid change lens system (patented) makes quick changing possible while the thermal lens keeps you fog free. The mid-level 20/20 is a hard plastic mask with clear thermal lenses to prevent fogging. The lenses can be changed with ease. Invert goggles are great to own. Always consider an extra lens with your goggle purchase.
