The Original 50lb Lead Wake ballast bag is designed for the wakesurfer/wakeboarder in mind. The use of these 50lb ballast bags makes it super easy to dial in, and fine tune, your wave or wake without having to deal with the hassle of filling big water bags or juggling your friends around. Because our bags are so compact, they can be conveniently placed in storage compartments out of sight and out of the way. Our bags are 100% hand constructed in California using 1000d Cordura material and are double machine stitched for strength and lasting durability. The innovative core include two layers of heavy grade vinyl with a load dispersing/impact absorbing foam layer between the shell so there's no hard edges. We top it off with an easy to grab 2" nylon strap. And we can't forget the good stuff...Don't let the name fool you, we use ONLY 100% recycled steel to fill our ballast bags!
