The Anon Tracker is a fantastic goggle for little skiers and snowboarders who love fun colors. Anon's ICT (Integral Clarity Technology) does a great job of keeping their lenses fog-free so they can see where they are going at all times on the mountain. New this season is the integration of Anon's MFI (Magnetic Facemask Integration) that allows you to attach an Anon Facemask (Sold Separately) to the frame of the goggles to help seal out the cold and snow. Dual Layer Face Foam keeps a seal across their face to seal warmth in and keep snow out. Full Perimeter Channel Venting keeps air moving through the goggles to prevent overheating. The No-Slip Silicone Strap prevents the goggle strap from sliding up on helmets to keep the Tracker right where they belong, on your little riders face.
