I have rented all the needed equipment for skiing (skis, helmet, shoes, sticks),
but the only thing which I couldn't rent was - glasses.
I needed to buy them, and as it turned out, the main problem for me was that my nose is quite wide,
so only some glasses were good for my comfort while breathing...
So I bought these as an jet-pilot looking CAIRN STRATOS ski glasses, S3 category, great vision in the sun and also in a fog.
