This is a new, highly technological, Cressi snorkel that has been designed specifically for deep fishing and free diving.The tube of the Corsica is characterised by the use of a new concept of special polymers that have excellent shape memory thus allowing the snorkel to bend against objects and then spring back into its original position.The mouthpiece in hypoallergenic silicone has been designed with a special anatomical shape that minimises any feeling of discomfort, even after prolonged use.
