The Genius OTG ski goggle from Cairn offers great comfort and a maximum field of vision, while being suitable for use with prescription glasses. It features a spherical double lens that works like double-glazing, isolating cold outside air from warm inside air. This greatly reduces the formation of condensation. For comfort, it's fitted with soft, warm double-density foam. An excellent OTG model suited to slim faces. This description is an automatic translation.
