The Sak Ballast Reversible makes it easy to transport your ballast or other items during competition. Reversible, it stows the ballast directly in the Kanibal Race II's pocket and allows the drain hose to be extracted, while also allowing the load to be distributed more evenly by attaching it to the front of the rucksack for greater comfort during the take-off access phase. Thanks to its hook fasteners, it can also be adapted to any harness by attaching it directly to the main links.
