About Anon Optics Realm Goggles: Okay, this goggle we have here is called the Realm, and this this the absolute top of the line Ferrari of goggles. Let's start out with the lens. This is a spherical dual lens, polycarbonate outside, propanate inside, anti-fog treated. What the polycarbonate does, keeps it very durable, very scratch resistant. Spherical cut, so you have maximum peripheral vision. Horizontal and vertical vision with unobstructed view. Next thing you want to notice, we have what's called a removable air mesh system in this one. You can actually pop this mesh out, when you're hiking the pipe or the back country. Keeps it completely fog-free, and air ventilation flowing through, so you're not going to have any issues with that, if you're sweating like a pig. Then you can pop this thing back in. Back in action. Triple-layer face foam, so you keep that seal. Keep the elements out. Amazing colors and graphics that Anon is known for. Hydra prints, applications on the straps, metal logo treatments, all the way through the whole line.
