I dive with both 15l and 12 l cylindersI dive with both 15l and 12 l cylinders. 12l dumpy ideal for intermediate dives where you don't need the extra gas and don't want to carry the extra weight of the 15's. Being Dumpy means diameter is the same so that you don't need to change the cam bands on your wing or BCD. Shame that they are not offered Oxygen clean.
