Mares knows that snorkels can be a nuisance to divers, which is why the Dual snorkel is made of bi-material with different softnesses, providing correct flexibility during use, without creating airflow interruptions, this means no more shaking snorkels on your descent, but also makes the snorkel highly durable with low-risk of cracking. The anatomical profile is highly hydrodynamic and reduces vibrations and noises during underwater motion. The mouthpiece is made of hypoallergenic silicone and makes it ideal for prolonged use during breath-hold-based diving excursions.
