these appear and feel very durable, but they have worked loose and come undone in the back both days i have warn them. a problem that has not occurred using my previous pair from walmart that were half the price. i have warn these old ones for over six months of extreme outdoor work in the florida sun. i only sought to replace them and upgrade because of the rusting of the metal clips. these new ones have been disappointing and cause discomfort in the middle of a busy and bustling work day. the clips don’t seem designed to grip and handle the pressure.
