Leupold Sentinel Polarized Safety Glasses - Matte Tan/Bronze Mirror - Your sight is worth protecting. The Sentinel performance eyewear meets MIL-PRF-32432A impact standards and guards your eyes with a swappable shatterproof lens. All three models come with a secondary clear lens, and they each have an adjustable No-Slip Bridge that'll stay put during even the roughest encounters. If you're a competitive shooter or defender of the peace, the Sentinel is vital to your kit. Features Daylight Max provides UV protection for optimal performance in bright conditions. DiamondCoat is a hardened surface coating that reduces surface scratches. Provides all day comfort with no-slip, soft-touch rubber bridge pads. Protects against manufacturer's defects for the life of the product. Eliminate the glare, not the adrenaline. Leupold's In-Fused polarized technology uses an advanced manufacturing process that fuses the polarization film between two of the lens layers. This process provides permanent polarized protection that won't scratch or deteriorate over time, so you'll never have to worry about slowing down. Guard-ion is a hydrophobic lens coating that sheds dirt and water for a maintenance-free, clear, crisp image. Made from ballistic-rated materials, all performance eyewear frames are ultralight, flexible, and maintain structure under stress.
