This is the ladies’ version of the Back Jac model, and it too is a rear expanding BC.
It offers the best buoyancy in the whole range of Cressi BCs. 
The conformation of pockets, harnessing and shoulder straps has been studied for the best fit on the female body.

Lady Jac has a special elastic bag retainer to keep the size small and to improve streamlining.

Lady Jac has also been designed to stow  weights in various pockets.

It comes with the Lock-Aid System (L.A.S.), consisting of two special slip-off weight pockets with mechanical safety release, each one able to stow up to 4.5 kg of weight.

Comfort is guaranteed by the soft outer of the back pack in special mesh and of the whole inner part of the BC. The elasticised camband is made in two pieces; the length can be adjusted and it comes with the famous Cressi Freematic system.

Accessories include two roll-up, concealed mesh pockets, two extra weight pockets (situated on the front of the bag), several stainless steel D-rings and flexible hose clamps.

A judicious choice of materials has made it possible to combine its extreme sturdiness with a smaller weight for air travel.
