Goruck.com - It's Not a Backpack, It's a Rucksack. Rucking is the foundation of Special Forces training and where we learned the way of the ruck. Proven in the toughest environments in the world and built to Army Special Forces standards, GORUCK rucksacks are the absolute best for everyday carry, rucking, and traveling. Every ruck we build is backed by our Scars Lifetime Guarantee.We believe rucking is the world's best exercise, and the Rucker is the best rucksack for rucking. Just add weight (we prefer Ruck Plates®) to your rucksack, and start training. With ergonomic lumbar support and an all-new, less abrasive fabric, the Rucker® is truly the gym on your back.
