A module designed and customized specifically for the JJ rebreather. The “Tube” weights fit perfectly into the frame tubes, eliminating the need for any additional pockets.

The 0.5 kg version is weighted on one side so you can precisely trim yourself, and has two holes for a string to pull the weight out, depending on whether you want the weight at the top or bottom of the tube.

They are cast from lead and then coated with a layer of plastic.
Thanks to the plastic coating, the weight does not scratch other equipment, has no sharp edges, and most importantly is safe for both humans and animals.
