These are actually the best goggles ever. I have ones with a Black Iridium lens, and just got the Lava Tempest with Pink Iridium for cloudy days. I ski mainly whistler blackcomb, and while the black iridiums are amazing for sunny days, I really need something a little lighter for all those cloudy days we get in BC. I have a medium size face (I guess?) for a girl and I wear em with a Smith Holt helmet. I usually put the strap under my helmet, but they also fit if you have the strap over top. The plush 3 layer foam is really comfy, they look super fierce and even hiking in light rain, fogging is a non issue. Really, what more could you want in a goggle?
