Finally have a few rides on mine, and I’m very happy with them. Have the Infinity Photochromatic lens. This is the first goggle I haven’t had any fogging issues with—and I’ve had the original 509 Ignites and the Ignite 2.0 S1’s. Tempest has really delivered on the simplicity of just put them on and they just work. The battery life is also as good as advertised. They also seal to my Fly helmet really well. I never felt the 509’s fit well with a 509 Altitude helmet, or the Fly helmet. The only small gripe I have is with the field of vision, but I quickly get used to them after having them on.
