The slim-profile design of the Revision Bullet Ant Tactical Goggle provides optimal facial fit, high-impact protection, wide field-of-view, plus helmet and night-vision gear compatibility. Equally comfortable with the strap worn over or under the helmet, the hexo-vents permit maximum ventilation, without any adjustment, for fog-free performance and fine particle filtration. Clear, neutral grey and high-contrast lenses allow for visual clarity in various light conditions.
