The soft, padded backpack has a strong grip rubber zone and a double camband to hold the tank firmly. Two large zip-up pockets house inside two mesh weight pockets and on the back of the BC, another two weight pockets mean the weight can be divided perfectly. The command for the purge valve on the back is situated on the bottom right front of the jacket.

All the D-rings are made from light alloy.
It only takes a few moments to fold up Flex and tie it with a special foldaway belt so it can be easily put into the special carry bag that comes with shoulder strap.
The very light frame of Flex and the anatomic style underwater translate into a very close-fitting and streamlined BC that offers very little resistance to forward movement.
