The Neptonic Systems snorkel is our all-time favorite for free diving, snorkeling and spearfishing because of its extra wide tube. It is extremely comfortable, featuring the perfect “J” design with a wide bore for maximum oxygen intake and smooth breathing. This snorkel is perfect for any level of experience in the water. It features silicone construction for a soft and flexible fit in any configuration, even under a mask strap. The mouth piece fits comfortably without placing stress on the jaw, even after long periods of time.
