I was a bit hesitant about the unusual fly opening but gave them a try. The elastic in leg openings seems about right to me, and I can certainly live with the odd fly. The fabric is soft cotton and I love that they come in numbered sizes, not just S/M/L which never seem to fit. What's more, the fit doesn't vary from pair to pair which I can't say for some underwear I've tried. For my money, the best underwear are those you put on in the morning and don't think about all day because they're doing their job. These are those.
