Not a confident swimmer but want to enjoy snorkeling?
If you're not a strong swimmer, then there are snorkeling vests available to give you that extra peace of mind. These will really help increase and control your buoyancy. Even good swimmers benefit from snorkel vests, taking the hard work out of snorkeling in choppy water.
Snorkeling vests come in two styles - vests with a front and back, and a horse-shoe style which has ties to hold it in place. Snorkel vests are not life preservers. They're designed specifically to help swimmers with buoyancy in the water. They are inflated and deflated by the wearer via a tube on the chest area.
