I'm recovering from a running injury and forced to water jog in the swimming pool. I did purchase the Aquajogger pro belt for men, but the blue belt wasn't long enough and the smaller black belt was putting pressure on my stomach. I called up Aquajogger and they said the Aquajogger Shape belt is longer (i.e. the blue portion of the belt). They also said the shape belt was unisex and not specific for women. Swimoutlet needs to change the name of this belt on their website. My girlfriend also tried this product and she is very small, and it worked well for her too. I'm very happy with the shape belt!
