As a Respiratory Therapist, I would strongly advise against the use of full face snorkels.
The last thing you want to do is re-breath your expelled CO2. You do it for long enough in these masks, you can pass out and potentially drown. Other stories have noted the potential for leaking. Just my 2 cents.
Recommend full face snorkel?
in Scuba and Snorkeling
