Review: Very good jammers - My son competes in swimming and these jammers have been a life saver. The fit correctly according to swimmers specification, the are not see through and the material is very strong.
Review: Improved performance - I was doing a little research on efficiency of tech suit over regular team swim suit. I found 1 or 2 seconds improvement you can expect when the swimmer compete 100 M stroke. My son was 0.07 or 0.04 second behind qualifying times. So we decided to try the tech suit hoping it compensate the time. My son tried this for the first time and he experienced a lot of improvement on his time at championship. I reduced 5 second on 100 breast and 3 second on 50 free. First , the tech suit repells the water instead absorbs it. The load to the swimmer becomes less. The suit has a special design/ materials to improve/stimulate muscles and it can help shorten the time.
