Full face masks for cold water diving

[Chris H]

You'll find that happens a lot in this sport.


Other Chris,  good info on the FFM.  Do you really find yourself concerned about the microorganisms in water?  There is no doubt they are there, but other than somebody asking how I could swim in Lake Michigan after the MMSD did a raw sewage dump, it isn't something I hear people talk much about.  Maybe because we don't have coms in our masks ;D

How are air shares and gas switches handled with a FFM?
