3C collar (Closing Comfort Collar)
3C Collar - Closing Comfort Collar: Collar system developed by beuchat to offer maximum comfort in any situation.

Collar made of a monobloc panel which has no assembly (no glue or overlocking points) and whose aggressive side of the fastener is turned outwards to avoid any friction.

In addition, a protective boss above the fastener  provides an extra protective layer. It also offers a wide elasticity of adjustment of the fastener  so that the tightening can be finely adjusted.

Finally, the position of the fastener  flap facing outwards has been designed so as not to damage the garment.
