If the issue continues, do not use the mask and contact your closest Decathlon store. • Snorkelling safety: Snorkelling is an easy and fun activity for all the family! Breathing through a snorkel is more physically demanding than regular swimming. If you feel tired, short of breath or dizzy, remove your mask and get out of the water.

If in doubt, consult your doctor. • What is the Easybreath?: The Decathlon Easybreath mask is the second generation full-face snorkelling mask created by Decathlon.
