the best fitting glasses I've ever worn motorcycling, they hug your forehead when air flow catches the flare, covers your nose comfortably, forms to your cheeks nicely, all preventing air flow to your eyes for less tearing and clearer view!!!! only problem I have is the flexing of glasses is the small lock piece to hold the changeable bows to glasses pops off and you there gone, thats the only thing that should be changed. other than that, i'll be ordering more!!!!
