It sports the French national colours only by chance. In fact the colours blue, white and red replicate an internationally recognised breathing exercise in freediving: A breath is taken during the five-second blue phase, it is held for 15 seconds (white area) and then air is expelled over 10 seconds (red area). With the help of this colour code, the freediver can concentrate fully on this vital breathing exercise without needing to count or use a stopwatch.</br><br/>http://www.amazon.com/gp/product/B06X9BJNC3
