There's nothing worse than a fabric strap that frays. Unlike a worn-in leather strap which actually looks good, no one likes a frayed fabric strap. And that's why we've spent quite some time during the R&D and QC process to make sure the loop surface of the Delcro experiences minimal fraying through regular use.
The loop surface of the Delcro has been expertly engineered to maintain its integrity even after hundreds of opening and closing action. That's a few years worth of daily wear before you see any significant fraying!
Note: While the loop surface of the Delcro should not fray from regular opening and closing action, the fabric surface (the side that touches the skin) can still fray, especially if the fabric is rubbed against a sharp or rough surface repeatedly, such as the sharp inner edges of a Rolex case.
