looking at the sidedraft flex and not sure of the difference of a "dry" snorkel. what is the splash guard feature and the snorkel keeper. thanks
LeisurePro S Dry means that when you submerge and your mouth is on the snorkel, no water will enter the snorkel. Splash guard mean the snorkel will give you surface splash protection from waves. Snorkel Keeper "keeps" the snorkel attached to your mask for use.
