The Women's Swimwear page brings together swimwear for women: one-piece swimsuits Arena, Speedo and TYR, racerback or crossover styles, chlorine-resistant models, legsuits, thermal swimsuits, and bikini tops and bottoms.

The swimsuit suited for laps, competition, or the beach.

The one-piece swimsuit

For swimming, the one-piece swimsuit is still the go-to choice: it stays in place during dives, turns and arm movements. The shape of the back determines shoulder freedom: the swimmer's back, which is very low-cut, frees the shoulder blades for freestyle and butterfly; the cross-back, like on the Arena Challenge, offers good support; the tied backs, like on the Arena Sunny Tie Back, can be adjusted to the body shape.

All the equipment is gathered on the swimming page.

Resisting chlorine

The chlorine in pools damages elastane: a standard swimsuit stretches and fades after just a few months of regular swimming. Chlorine-resistant polyester swimsuits last much longer: it's the right choice for swimmers who train several times a week. Ranges made from recycled fibres, like the Speedo Eco+, recycle plastics, for example. The legsuit, which extends down to the thighs, provides more coverage and streamlines the silhouette.

Choosing the right size

A swimsuit should fit snugly: a swimsuit that's too big lets water in and slows you down. You should choose your size according to the brand's size guide, taking into account your bust measurement and torso length. Swimsuit tops with underwire, like those from Freya or Elomi, provide true support for fuller busts. Rinse your swimsuit in clear water after each session and lay it flat to dry in the shade.

Good deals

Good bargains can also be found in good deals, promotions, clearance, sales, and Black Friday. The new arrivals showcase the latest collections, and items shipped within 24 hours are processed and dispatched in 24 hours. The key events of the year follow a stable order: Black Friday at the end of autumn, the end-of-year holidays, the winter sales, the French Days in spring, followed by the summer sales and back-to-school season.

Frequently asked questions

Racer back or cross-back: which swimsuit to choose?

The racer back, which is very low-cut, frees the shoulder blades and allows full movement of the arms in freestyle and butterfly. The cross-back, like on the Arena Challenge, offers better support for the bust.

Which model for a plus-size swimmer?

Plus-size models have wider straps, a more covering back, and sometimes a reinforced lining at the front. They hold the bust well during arm movements without hindering swimming.

Bikini or one-piece for swimming?

The one-piece swimsuit stays in place during dives and turns, which is why it’s preferred for training. A sporty bikini, with crossed straps and a fitted bottom, is suitable for relaxed swimming or open water.

What is a legsuit in swimming?

The legsuit is a one-piece swimsuit that extends above the knee. It streamlines the thighs, provides more coverage, and improves glide, both in training and competition.

How to make a swimsuit last longer?

Rinse it in clear water immediately after the session, wash it by hand without wringing it out, and lay it flat to dry in the shade. Alternating between two swimsuits gives the fibres time to regain their shape.
