i Purchased 8 pair of these in Iraq. I initially tried medalist and found they stretched to much in the legs. I have now worn these 8 pair for over a year and they have no rips, or signs of wear. the still fit snug, don't ride up and are very comfortable.
These are the most comfortable undies I have ever worn, they are very well made, Im sorry I only bought two pair so I am going to through out all my other jocks and replace them with Under Armour
