Biojac BCD

The BIOJAC BC is made with BioFlex - a patented "living fabric" that stretches, flexes and conforms to your body. BioFlex can stretch while remaining airtight allowing us to use smaller air cells. This means less bulk and drag with more lift.


A perfect fit, for any body.

Nowhere is this more important than with BC's, where comfort and freedom of movement must be balanced against function and durability. Responding to this challenge our engineers created BioFlex - a unique "living fabric" that stretches, flexes and conforms to the body.

BioFlex is an extraordinary fabric, which stretches, fully inflated up to 30% over conventional nylon or polyurethane BC materials. The idea being that id a material could stretch while remaining airtight, you could make smaller air cells, creating less bulk and drag underwater while achieving high volumes of lift when required on the surface.

BioFlex eliminates chest squeeze, conforms to the diver's body and provides a slim, body-hugging profile.
