A feeling of fatigue and a build-up of CO2 in the respiratory system can lead to potentially serious consequences, even during low-impact physical activities like snorkelling. That’s why SEAC abides by two fundamental principles in designing its full-face snorkelling masks:the user should need to employ the least possible breathing effort, comparable to natural breathing, out of the water and in a relaxing situation;and the level of residual carbon dioxide CO2 inside the skirt while inhaling must be well below the safety limits.
Even though there is no specific European regulation governing the manufacture of full-face snorkelling masks, SEAC® has developed a series of specific tests that comply with the values set forth by the following European regulations:
