Our long swimsuits give you the coverage you need for a little extra protection, fitted with chlorine resistance to give you more than 200 hours of swimming time without suffering from the wear and tear common in low-quality long swimsuit alternatives. We give you the pick from a variety of vibrant colours while keeping you comfortable during your laps and as you lounge by the poolside and stay nice and warm with our quick dry swimming towels.

We’ve got something for everyone. Are you a keen swimmer who thinks nothing of a quick 100 lengths post-work, or looking for the occasional dip in your local swimming pool seeking some relaxation? We’ve got the look for you. Browse our women's swimsuits and long-leg swimsuits to suit a variety of body shapes, styles and tastes.
