The Goruck Rucker 4.0 is built specifically for rucking training... If you train hard on dirt, grass and concrete, the Rucker 4.0 is the tool you need to get stronger. The Goruck Rucker 4.0 is also (and more simply) an ultra weatherproof backpack. Like all Goruck backpacks, the Rucker 4.0 is made entirely in the United States, by the iconic American brand Goruck, which draws heavily on military experience. That is to say, Goruck selects ultra-tough materials, which ensures infinite durability for their backpacks.
The Rucker 4.0 has been improved by the American brand to make the maintenance of your equipment even easier. In particular, Goruck has redesigned its zipper system (considered too fragile by some users): they have replaced the inside zippers with velcro and have removed the outside front pocket.
The Goruck Rucker 4.0 is ultra comfortable, with improved padding. It also has ergonomic lumbar support, and the fabric on the back panel and underside of the shoulder straps doesn't cause friction burns. Bottom line: walk, run, jump and travel in comfort with the Goruck Rucker 4.0.
