If your old paintball goggle / mask lens is looking a bit scratched and tired then you really need to consider changing it in case time, weather and direct hits may have caused the lens to weaken. You may also want to consider changing to a thermal ‘double glazed’ lens to combat fogging up. LiPS sell all major brands of lens; Dye i3, i4, V-Force Grills and Profiler, Empire E-Vents and E-Flex, Proto and JT Spectra. Good paintball masks and lenses are essential paintballing equipment.
