Lobster collar base 4 kg designed not to overload the freediver's neck during the dive. Its shape, which is highly hydrodynamic, makes swimming much more effective by allowing greater distances to be reached with less effort.

These weights are attached by means of silicone inserts that, when embedded, allow the segments to move following the movements of the vertebrae, without restricting the swimmer's movements.
