I have 4 of their nylon Natos, all 22mm that I wear on my 40mm Everest and Dreadnought Voyager. I've been using them for probably a couple of years now. I really like the look of their canvas straps, but I've never found a definitive answer as to how well they withstand long term daily wear. The two watches I wear mine on tend to be worn for weeks at a time, mainly 24/7, with others coming in brief rotation at weekends/evenings. The areas that concern me are the finishing stitching around the pin holes for the buckle and the pointed end that passes through the buckle and keepers. I did have a problem with one of their Natos, with fraying at the pin holes and threads coming away after very little wear. I contacted them, and continued to wear the strap for a while to see how the problem might develop, and Haveston's customer care was exemplary with a replacement being sent ASAP. The nylon straps are thinner, and the keeper retaining part of the strap you have removed doesn't bulk the strap up enough to require removal, although I can see why this is needed with the canvas. I'm interested to see how your straps fare with some decent wear time on them.
