Whether you’re swimming lengths, paddleboarding or chasing the kids on the beach, these are the best swim bikinis that stay in place and combine comfort, support and performance – without compromising on looks

Swimming lengths before breakfast, jumping waves with the kids or relaxing by the pool all call for swimwear that does more than simply look good. The right bikini should stay put, feel comfortable and give you the confidence to move freely, from paddleboarding and surfing to a leisurely beach day or perhaps a water park.

And we get it; choosing one isn’t always easy. With so many styles, cuts and fabrics available, it’s worth thinking first about how you’ll wear it. If you’re planning to be active, look for supportive designs that won’t shift while you swim or take part in watersports. If your priority is relaxing by the pool, a flattering fit and a touch of glam may be higher on your list. And fabric, well, that’s just as important too. Many swimwear brands now use chlorine-resistant, UPF-protective and recycled materials made from discarded fishing nets and ocean plastics, helping your bikini last longer while reducing its environmental impact.

To help narrow down the options, we tested 12 bikinis for fit, comfort, support, quality and performance both in and out of the water. Whether you’re after maximum support, flattering coverage or a bikini that looks as good as it performs, these are our favourite sporty (and confidence-boosting) picks for summer.
