Cressi America Snorkel
This snorkel is designed specifically for the needs of free divers.
The ventilation is excellent, because the tube is shorter, has a large bore and is a well-connected anatomical shape without sharp curves.
The tube is made from flexible, black material, and a soft silicone mouthpiece fits into the end; this is a swivel mouthpiece so it can be placed at the correct angle for comfortable and long use.
The height adjustable mask strap holder has a modern catch.
