Compression shorts or the UnderArmour BoxerJock, which is similar. I don't like the straps on the jock.
Again, thanks ... much appreciated feedback ... I've always worn jock, but see many others in compression shorts ... so I have now worn comp shorts for last few days .... doesn't seem my package is secure enough, but it is (no problems running or on stairmaster) ... I think I like comp shorts ... but will still wear jock sometimes. Thoughts?
