The M size weight pocket will allow you to carry up to 6 kg of weight, their construction makes them very compact. This is a perfect choice for slightly-build people or for divers who need only a thin wetsuit.
The weight is carried in the inner holder equipped with a strong handle.
Such a solution makes it easier to carry and manipulate the weight and significantly improves the safety.
You can simply take out the weight from the pocket at one time and pass it to the boat crew to make it easier to get on the boat, without the risk of dropping the weight.
