I purchased the size according to the size chart, wish I had ordered a size smaller. Feels like too much material. They are nice though.
Nothing stays where they’re supposed to.
Very pleased with Crossfly! I’m a fan. Definitely go one size down if you’re between sizes.
I bought them for my son as a birthday present but he's a young man of few words when it's about his underwear. He hasn't complained so they must be ok or more than ok, as I bought them for supporting his 'crown jewels' more than for anything else. What I'm really pleased about is that he received them quickly by post, as he's living in the middle of nowhere in the Highlands of Scotland. Well done postie.
The best underwear I have ever worn. So comfortable and so clever!
So the material of the underwear feels great no complaints there. I do experience some ride up in the thighs so that’s not so pleasant but I can deal with that. So here’s where it’s a little problematic, let’s put it this way…anytime my not so little guy gets “happy”, it pops out the access fly and says hello. That would be fine and acceptable if it occurred when I’m about to get action but let’s face it men randomly get “happy” so that’s where it’s a bit problematic. Not sure if this issue wasn’t taken into consideration when designing these underwear, but it’s kinda strange to me that it wouldn’t be a factor when designing them. I can’t be the only person who has experienced this either but yea it’s a pretty big draw back to the underwear.
