We are Gruff + Tumble. We make premium underwear built for real size men. Why is it so hard? As passionate athletes and busy professionals, we asked ourselves this question - "why is it so hard to find quality boxer briefs in larger sizes?" Our answer is making innovative underwear for larger frame performance. Gruff + Tumble speaks directly to how real size men live, work and sweat. We started this brand to support active big men. We offer those who enjoy going hard, at whatever they do, a premium option of something different. Our daily wear boxer briefs come in three styles that cover the fundamentals – Sport, Pleasure, and Grind. We kept it simple and focused on comfort and mobility for these essential pursuits. Whatever kind of day is ahead, we've got you covered. For the past 14-months, we’ve gathered measurements and had honest conversations with men and women. This data-driven approach informed our entire construction process. Then we added the sexy.
