I work in law enforcement and am constantly on the move. I lost the first pair of these I bought a while back. I attributed it to the length of the band. After receiving this latest pair, I again think that the band length is too short. I often inadvertently fling one side or both sides over my shoulder. I recommend extending the rubber band a good four inches to make them hang a bit lower. I also recommend adding hinges that allow the glasses to bend the corners of the lense piece (inward). I have another pair of clics that have a rigid band that bend at the corner of the outside lens hinges that are awesome. This recent pair does not have that hinge. Hope this helps! I also bought my wife a pair recently. She loves them and gets asked about them all the time.
