There's a reason that at least 50% of the guys at all the gyms I've been to wear these. And it's not because they are trendy.  Guys might wear trendy to impress a date but they won't wear trendy if it doesn't give the proper support at the gym.  And while these don't replace a standard jock, they do provide an incredible amount of support.  Holding everything in place while not feeling restrictive is the hallmark of these remarkable boxers. These also do a remarkable job of wicking away sweat and stink.  They also dry very quickly.  I'm not sure what they do to the fabric to keep it from absorbing odor but I can sweat in these all day and they don't stink. Amazing.
