I get the purpose of a jockstrap is to hold ur junk from bouncing around but these are extremely small, esp. for American men. I know jockmail says to follow their chart and u shouldn’t have a problem with sizing, but they’re made in Asia and believe the pouches are too small for American men bc Asian mens junk is much smaller. They seem to be made good but I couldn’t wear them, and it would cost more to ship back than I paid so I’ll try to get my 13 yr old son to try them on. He’s tall and skinny so they’ll probably fit him better. Always check before u buy underwear on Amazon, if it’s made or coming from Asia u can bet the pouches are gonna be too small for American men! .
