The Empire e-Flex comes with the proven Vents quick change lens system and thermo-foam ear pieces from the E-Vent paintball mask and mated it with the flexible skirt of the ProFlex with a little touch of comfy Spectra foam. The Vents lens removes in seconds and the clear, dual-pane design provides maximum viewing angle and visual clarity while the comfortable ProFlex foam assures the most satisfying fit. The ultra soft and flexible ProFlex style skirt offers excellent breath-ability and voice projection and has been tweaked to produce a smaller profile. The Empire e-Flex Goggle provides you with maximum comfort, super light weight, superior optics and excellent protection...simply put, BEST IN CLASS!
