The Unlimited II OTG Goggles are built specifically to fit over prescription glasses without pinching or fogging up halfway down the run. An integrated RAM Air System manages airflow inside the frame, working alongside a NoFog lens treatment to keep both the goggle lens and the glasses underneath clear as temperature and effort change. A 2-layer molded face foam with a fleece lining seals out wind and wicks moisture, so the added layer of glasses doesn't mean added discomfort. What Our Gearhead(R) Experts Are Saying:"I wear glasses every run, and these are the first goggles that never fogged up on the chairlift ride."
