A big +1 to ChickenFried and KatieKatie...... Under Amour is the way to go....... Constant issues for me with boxer briefs was the riding up, UA's stay the best, especially the 6" inseam or more..... You'll spend $20 a pop on them retail at Sports Authority or the likes...... If you hit an outlet mall like the one in Cypress, you can get them for half that...... And if you search enough online you can as well......
While they are pricy, they LAST much longer than any other boxer briefs I had......
