The Corsica Snorkel is a new snorkel from Cressi designed for spear fishing and free diving, but is still perfect for the scuba divier who wants a foldable snorkel. The Corsica is made from special polymers that have excellent shape memory allowing the snorkel to be bent against objects such as rocks, wrecks and overhangs and then springing back to the original shape without damage.  The hypoallergenic silicone mouthpiece is anatomically shaped minimizing discomfort; even after extended use.
