Goruck GR1's are designed and field tested by Green Beret. Using the most durable material possible, D1000 Cordura, the team builds rucks that utilize the best aspects of the rucks issued by the US Army Special Forces. GR2 is big, tough and efficiently stores everything necessary for excursions across time zones. It houses the gear, clothes, shoes, laptops and electronics necessary for multi-day adventures. Sized to carry on a C-130, 747, or whatever plane, train or truck you choose. Travel hard, travel far.
