It was very expensive and not very comfortable. I tried it several ways, and I am fairly small. I can't imagine it being very comfortable for a large person.

I use it to jog in deep water for no-impact running. It adjusts easily to a perfect fit and is very comfortable. And I love the purple color!

I am a runner rehabbing a hamstring injury by pool running. I decided to try this new version of the AquaJogger for women.  It is definitely more comfortable and made of better materials than the original model which dug into my ribs and shifted position.  It keeps me upright with feet off the bottom even in a small pool only 5 and 1/2 feet deep.  I use the separately sold extension line which clips onto the belt to anchor myself in place.  It is allowing me to maintain cardiovascular fitness while my hamstring heals.  The only thing I don't like is that it is hard to attach the clasp at the end of the line to the thick belt.
