Something new and different these are a gift from a friend. Super bright and fun. They have a button fly which is different for a brief. On the plus side they come with a extra button just invade you bust out the one that’s there, and you may actually! These fit perfect but have limited junk space, tight and snug at times found myself adjusting a lot. I would buy them but size up to see if it makes any difference. Hope you all like.
