Our Sandbags are the toughest ever built. We beat the hell out of our Sandbags for two main reasons: (1) to prove they’re the toughest Sandbags on the market and (2) we don’t know any other way. Made of 1000D Cordura ® and proven across 1,000’s of miles of stress at our Events and in garage gyms all over the world, GORUCK Sandbags are built in America and built to last..
