Nice width. Flexible yet supportive. They replace the too elastic ones. The plastic buckle is not the prettiest (fashionable) of buckles. However, I like that I don't have to take it off at airports for TSA. It also doesn't scratch the paint or finish of my hobby projects. I've only had them recently so can't comment on durability but they seem to be made out of durable material. The area pinched by the buckle shows slight signs of wear after just a few weeks. The time will show.
