The Striketeam XTO features closed-cell face padding for maximum durability and ease of cleaning. The open-cell vent foam provides filtered ventilation, allowing the humid air to escape, but prevent airborn particles for getting in. All Striketeam goggle components are heat and flame resistant, including the face padding and vent foam, and the lenses provide maximum impact protection and optical clarity. The roomy Striker frame is designed to fit over most eyeglasses. The one-piece wrap-around strap features the patented ESS Speed-Clip system, which adapts to all wildland and rescue helmets and facilitates quick strap adjustment, even with gloves on. All Striketeam goggles are compliant with ANSI Z87.1-2015, U.S. Federal OSHA and wildland fire equipment performance requirements, including the 350-degrees F for 5-minute oven test. This line is considered Primary Eye Protection by NFPA 1500. Striketeam goggles use Striker Series lenses, all of which provide 100% UVA/UVB protection and distortion-free optical clarity. They meet and exceed ANSI Z87.1-2015, the U.S. Military .22 caliber ballistic impact test MIL-DTL-43511D (Clause 3.5.10), and CE EN 166.
