This Hydro-Pro SeaClear snorkelling mask from Bestway uses dual dry top technology and tinted lenses, making it perfect for surface snorkelling. The mask covers the entire face and features 2 built-in snorkels. It is designed with an easy-adjust buckle. The excellent silicone provides a comfortable, secure fit and the ability to equalise the pressure while diving. The dual airflow technology ensures that you can inhale and exhale through the nose and mouth with ease as you breathe in through one snorkel and out through the other. Additionally, the full dry top technology ensures that no water can enter through the snorkel with an adjustable nylon strap for the perfect fit.
