Review on 🏊 ESONE Open Water Swim Buoy - Brighter, Lighter, and Safer for Swimmers (15L) by Chuck Chen

High quality safety bladder. No storage space, but what I needed most was visibility and buoyancy. On a recent Caribbean vacation, I swam in open water and snorkeled near a few resorts. The boat current was quite strong. I was confident enough to focus on the bottom and not go crazy every time I heard the sound of a boat. Most comfortable with a short strap. Especially when used with fins. I'm not a triathlete so can't comment on how it performs or slows down compared to others.
