Perfect for virtually all weather conditions. The rose Prizm lenses which for the basis of the Sapphire lens increases contrast and improves on what the naked eye can see in low light conditions. The mirrored sapphire tint on the rose makes the goggles suitable for sunny days as well though. Apart from that, design wise, I love that: 1) others can’t see your eyes through them 2) the flat lens look stylish imo 3) the rubber on the inside of the strap helps it stick in place on your helmet/beanie 4) the goggles unfog very quickly after you bring them down from the top of your hot head/helmet/beanie back onto your eyes. Very satisfied.
