American Flag Workout Shorts. Ranger Panties have a long history in our military as our badass Army Rangers would wear these training shorts during their PT. Today, Grunt Style has created its own style so that you can continue to kick PTs ass and train harder than before. Don't be afraid to show off your hamstrings and that heavy load you carry! The sweat-wicking fabric of these shorts makes them the perfect addition to your collection of workout clothes and the stars and stripes make these the most patriotic shorts you will ever own.
