The hood uses 5/3mm Quantum Stretch construction. Why is the top of the hood vented? The double-coverage vented top is designed to help manage air that can become trapped inside the hood during a dive. Does the hood have a face seal? Yes. The hood features a skin face seal around the facial opening. How do I choose my size? Measure around the forehead and neck and compare both measurements with Akona&';s sizing chart.

Care & Maintenance Rinse the hood thoroughly with fresh water after diving, especially after exposure to salt water or chlorine. Allow it to air dry completely away from direct sunlight or excessive heat before storage. Avoid folding or compressing the hood for extended periods, and periodically inspect the seams and face seal for wear or damage.
