Just in time for Duluth's Big Dam Birthday, you can cover your rear and celebrate a rollicking good time all at once. It has the same 6.5-oz. 100% cotton fabric, generous fit and functional features as our other tees, including extra length in the body to prevent Plumber's Butt. It even coordinates with our "Party Buck Naked" underwear print running right now – though we suggest checking local ordinances before partying pantless.
