FROM BAGHDAD TO NYC GR1 was built to thrive in Baghdad and NYC and has been tested and proven by Green Berets to meet the life or death standards of quality, toughness, and performance. It has proven itself the world over and earned its “Greatest Of All Time” status the hard way: one deployment, one event, one trip, one mile at a time. 1,000 Events/year, 175,000+ participants, and 200+ Special Forces Cadre later, the GORUCK Challenge is the most significant quality control program of its kind. No other bag is consistently put through more abuse, and GR1 thrives. The GR1 is built with a minimalist approach in mind and includes only the necessary features of an everyday carry rucksack: a bombproof laptop compartment, opens flat for easy packing, built with Special Forces grade materials, and soft but tough 210D CORDURA on the back panel and shoulder straps so your ruck doesn’t irritate your skin or chew up your apparel. Proven to Special Forces standards, GR1 is synonymous with the best of American Manufacturing. Each GR1 is built to last and comes with our Scars Lifetime Guarantee. Features Quick access zipper pocket under the top handle (featured on Allegiance Flag, Black, Steel, Black + Red, Ranger Green, Ranger Green + Black, Coyote Brown) 210D Back Panel and Shoulder Straps: Zero abrasion on fabric and skin. All-new 210D HT (High Tenacity) CORDURA® on the back panel and underside of the shoulder straps doesn't irritate skin or chew up apparel. The Allegiance Flag rucks were constructed in accordance with US Flag Code, with excess material during the flag making process from Allegiance Flag Supply, and no flags were cut or destroyed in the making of the GR1.
