I used this to extend my daily lap season here at the end of Long Island, New York in an unheated pool. The suit was fabulous, extending my season by at least three weeks. I am small 105 lbs, not a lot of fat, and I was still comfortable with this suit after 1/2 hour in 57 degree water. THe suit is well made, you can velcro the neck to keep the cold water out, the material is lightweight and the fit is great. A lot of suit for the price, Highly recommended.
I love how lightweight the suit is--I was worried at first that it wouldn't do the job, but it has exceeded my expectations.
