My husband has a belly that takes his jeans down and therefore pulls the back of the jeans down also.  This causes a plumber's crack.  Well, the 527s have the low rise in the front and a high rise in the back and this takes care of the problem.  I knew there had to be something out there to cover his parts. I have spent hours online looking for a solution.  Even ordered other styles that didn't fit.  So I have finally found the answer.  Thank you so much.  My husband doesn't much care, but he hasn't been the one with the rear view.  Thankssssssssssssssssss. .
