Love these glasses! Having tried several sets of glasses over the last few years I got tired of either running clear lenses, swapping lenses or having to take them off once it got too dark. Read a review of these and thought I'd give them a go and wasn't disappointed. They're really comfortable with plenty of adjustment in the nose area. They stay put when your in the rough stuff and I'm a sweaty soul so normally specs slip. The photochromic lenses work well and more than fast enough for me. In fact I had to take them off to begin with as the change was subtle but makes a big difference and it's so nice to be able to run one pair of specs for all my riding. Got a nice little hat on the pack too.
