For younger divers, Mares offers this jacket-style buoyancy compensator made from hard-wearing 420 denier Cordura.
It weighs only 1.8kg, and features include three dumps, two pockets, two D-rings and a cam-band that adjusts for slimmer cylinders.
One size is said to fit ages 8 through 12, and the price is £204.
