I bought these glasses on impulse last year. From the outset I was impressed by the quality and feel of them (the slip case could be better though). I have used these for 4 weeks for snow sports; one week skiing for myself and three as an instructor and they have been faultless, even in bad weather they have performed well. I really like the removable inner rubber 'goggle' surround as this allowed me to ski tour without the goggles steaming up too much and easily replace it for Alpine or powder. I have not used the elastic headband as they fit nicely under my lid without it. Overall: Comfortable, effective, stylish and excellent for the price.
