I love the fit of the muscleback. So easy to get off when I'm cold. Washes well..No bad points as far as I am concerned

Lovely pattern and colour.Swimsuits are always a snug fit I always go up a size

High quality, lovely design, beautiful colour; it looks stunning in the sea. I love fast, open water swimming and this product makes it even more enjoyable..The only downside is the sizing but thatÂ’s often the case with swimming costumes. IÂ’m wearing UK dress size 10-12 and yet had to buy size 18 (!) so that itÂ’s comfortable and not restrictive. It took two returns to get the size right but the company were brilliant about it. IÂ’ll try to remember for the next time.

The fit around the waist is pretty good.After only a few swims the elastic around the legs are saggy. Disappointing. The options available in style and colour are limited
