Hi, this is Bruce Justinen, with SEASOFT SCUBA, just wanted to answer a couple of questions. The SEASOFT Weight Harness release system is a sealed release. This means that sand or other debris cannot foul up the release mechanism. A spring is sealed inside a fiberglass/nylon casement, when you pull the release handle in a downward motion, this spring pulls the side release buckle edges away from the catch. And your weights are released. The pockets will comfortably hold 15 lbs. each and additional non-ditchable Trim Pockets will hold up to 5 lbs. each.
Also, every part of the SEASOFT Weight Harness is adjustable, if you are tall, short, big, small, everything is adjustable and the weight pockets can be moved forward and backward for the perfect placement.
I hope this information is helpful.
