Carrying this partly DiverTec Zulus. Over 2-3 years and not fray. The tapes are very stiff and stable. They are also a few cm longer than Straps from other manufacturers, which is very important for large wrists. If they are dirty times, I wash them easily in the washing machine at 30 ° with my sport / outdoor clothes with (without spin cycle!) And they look like new again. Have seen many Natos / Zulus obsessed, they are in my opinion the best. (Maybe not for small wrists and watches with a small diameter.)
