You’ll want a BUBBA™ Snorkel if you’re big or little. Its water deflectors up top mean no salty snuks in your gob—& the bottom reservoir with purge valve makes clearing a breeze.
 
OR, for performance snorkeling with a little extra ptuey to clear a double down tube, MoflO2™ is your snorkel of choice. Invented by me, SB, the MoflO2™ Snorkel delivers fresh air on each breath, so you’re not recycling CO2  on your way out to the far reef.
