Purpose-built for rucking and rucksack training. If you train hard on dirt, grass, and concrete, Rucker is the tool for you to get stronger one rep and one mile at a time.

The Rucker® is now upgraded to make it even easier to maintain your equipment. Gravity + USA Cast Iron Ruck Plate + Concrete = too many zipper failures.

It is the most comfortable rucksack ever built with upgraded padding on the top of the plate pocket for bear crawls. It also has ergonomic lumbar support and the fabric on the back panel and underside of straps does not cause friction burn.
