I tried a pair of these on in Sport Bike shop in Leeds in a 36” waist and the fly button popped off. The staff fitted a new one in store. The fit perfect but when on the bike I was concerned they might feel tight around the waist so I ordered a size 38” waist. I now need a belt but they are super comfy when riding the bike. I’ve just came back from a 9 Day ride around the Alps and they have been perfect. Super comfy and when off the bike they feel great for popping into cafes etc instead of bulky adventure trousers and big boots. They never felt too hot or too cold. When itv rained or hot really cold I just put my rain trousers over the top. They take up way less space in the panniers too if you want to whip them off and wear shorts when off the bike. However on the last day of riding the fly button popped off and into a urinal. There’s clearly an issue with the buttons. I’m just going to order one online for a couple of quid and fit myself which will take two seconds, otherwise these would be 5 star all day long.
