Can you advise which vests have a one handed valve movement to easily release the air for free diving. I believe some require the insertion of the cap or other small object which must be used to deflate and thus require fumbling in the water and the use of two hands (i.e. the newer Blue Reefs)?
Monica s The snorkel vest that we carry you do not need to insert anything in order to operate. The Blue reef vest as well. Just type snorkel vest into the search engine and some options will come up
