Purpose built for rucking and rucksack training. If you train hard on dirt, grass, and concrete, Rucker 4.0 is the tool for you to get stronger one rep and one mile at a time.
The Rucker® 4.0 is now upgraded to make it even easier to maintain your equipment. Gravity + USA Cast Iron Ruck Plate + Concrete = too many zipper failures. We can’t build better zippers to withstand this. Nobody can. So, we replaced the interior zippers with velcro and removed the front exterior zipper pocket.
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.
Lumbar padding supports the natural curve of your back
Featuring custom Electric Pink top, bottom, and side handles and interior + exterior zipper pulls
Hi-vis reflective stripe across the front for safety
4 padded handles: top, bottom, and both sides
3 rows of external MOLLE webbing on the front and side let you customize your ruck, like adding a Padded Hip Belt
Frame Sheet supports the integrity of the pack as you weigh it down and allows you to carry a heavier load more comfortably
Interior d-ring and hydration tube exit port under the top handle of the ruck
YKK zippers with silent, glove friendly zipper pulls constructed from parachute 550 cord
Opens flat so it's easy to pack and organize. Special Forces medical rucks share a similar design.
