A classic “J”-style snorkel that has been tried and true, the simple design makes this snorkel almost bullet proof and reliable compared too many of the newer hi-tech snorkels on the market. No fancy valves on top or bottom, if you can blast clear a snorkel than this is what you want. Mouthpiece material 100% high quality hypoallergenic liquid silicone. The tube material is 100% high quality liquid silicone. Differentiated-section tube designed to ensure excellent breathing and allow the quick and effective expulsion of water. The choice of 100% silicone is essentially due to two aspects: it is the only material that does not change its characteristics and behavior with the temperature and it is the only material that has memory to return to its original shape even after being deformed for long periods. The Seac Liquid Freediving Snorkel is designed specifically for spear fishing and diving. The ergonomic designed tube is comfortable and helps streamline the divers profile in the water. Snorkel includes an easy to use quick disconnect snorkel keeper and is available in multiple colors.
