These are great. They fit very well, are breathable, and don’t ride up or move around during the day. The pouch is especially good for running. I imagine it would be great under board shorts too. I'm a 34 waist, but I purchased the medium because I don't like loose-fitting underwear. They are great for me.
Turq underwear has now become my favorite underwear for all occasions. The underwear keeps everything in place for office work, working out, or just relaxing at the house in nothing but my Turqs.
These are the only underwear my 20-something, active boys wear! Love them.
