You can send GORUCK gear to hell and back and it'll come back looking unscathed and ready for the next adventure. They built their original Rucker to be the best rucksack in the game, and over the years they've evolved and perfected their design for optimal performance. Fast forward to the Rucker 4.0, a medium-size rucksack loaded with features and manufactured to Special Forces standards. After hearing about how even the toughest zippers fail when slammed between a cast-iron Ruck Plate and a concrete sidewalk, they replaced the plate pocket zips with velcro closures for even more durability. Don't let the performance-readiness fool you, though—this pack is versatile enough for everything from endurance hikes to riding your bike to the office.
