Snorkel question.. I know I know... Had a boat dive yesterday where the captain wanted every diver to have a snorkel. My wife and I did not as we normally don't use em even if we need to surface swim a bit. He didn't raise a stink about it but said next time we should have one in the bag just in case. We were talking about getting one that rolls up we can chuck into the bottom of our mesh bag to keep on hand in case we have that situation come up. Who uses one and can recommend something that would work to take up the least amount of space as possible.
