Large Tough-As-Nails Cordura Sandbag

9X World's Strongest Man veteran, IronMind's Tough-As-Nails Sandbags have quickly established themselves at the world's top strongman contests around the globe, as well as in serious gyms worldwide. Rock on, indoors or outside, they're made for tough stuff, like lifting, carrying, and loading--and unlike a stone, they allow urban dwellers to do cavemen-centric training anywhere. Plus, they train your grip each time you work out.
