Cons:
I got the XXL size buoy, which I don’t believe is currently available. Loaded with 3-4 water bottles it seemed to add 30-60 seconds to my training mile time. The drag is slightly noticeable, which is not a big deal on a training swim.
I've got one of the large ones also... its a drag.
The smaller units were provided and required for all the swimmers in this 21k swim I did in Sweden on Aug 4. We had a bit of a head wind, but everyone wore them. They do add a bit of time, but are hardly noticeable.
