Thank you for this article. I was very sorry to hear about Ms Peacock but after reading it I will be very cautious. I've been on 4 snorkelling holidays over the last 15 years so not very experienced and have been through 2 sets of snorkels. I'm always adjusting it bc I feel I can't breathe (bit sensitive about this bc I am asthmatic) and have been planning to buy a full face mask.
Thank you again, from Australia
