A close-riding, frameless goggle like the Contour RS usually sacrifices something to fit that tight against the face, but venting doesn't have to be it. The Sario MIPS Helmet's Stack Vent still lines up with the Contour RS's own top vent even at that smaller scale, so warm air clears at the source instead of pooling behind a lens that already sits closer to the skin. What Our Gearhead® Experts Are Saying:"I wasn't sure a goggle this compact would still catch the helmet's vent, but it does, run after run, without a hint of fog."
