What Our Gearhead(R) Experts Are Saying:"I grabbed these for stormy days at Brighton, and the Perceive lenses seriously cut through flat light better than anything I've used before. Swapping lenses is intuitive, and the MFI mask locks in place without ever fogging me up. Plus, they work perfectly over my prescription glasses-huge bonus."We ride harder and longer when our vision stays sharp and our face stays warm, and the Anon Nesa Snow Goggles + MFI Face Mask setup keeps us locked in on both fronts. Anon's Perceive lens technology makes the snow's textures pop, so even in mixed conditions, we can read terrain with confidence and precision. When wind picks up or flakes start flying, the included MFI face mask magnetically clicks into place for complete coverage-no awkward gaps or foggy buildup. With a cylindrical lens shape and a semi-frameless design, the Nesa goggles balance style and performance while maximizing field of view. Built with comfort in mind, the medium fit plays well with small-to-average faces and fits cleanly with helmets. A bonus lens preps us for changing light, and the full-perimeter venting and anti-fog coating keep things crystal clear lap after lap. Over-the-glass compatibility makes them a solid pick for glasses-wearers, too.
