Silicone with Marseillaise stainless steel buckle.

Because it is made from a stretch material, the belt automatically tightens up during descent, when it generally loosens due to abdominal pressure and the reduction in the thickness of the wetsuit.

Consequently the belt always fits snugly against the diver in every phase of the dive.

The Marseillaise stainless steel buckle has a tilting check pin that fits into the holes situated at regular intervals along the belt.

Secure grip and quick emergency release.
