Love it!!

Not totally sure about the chlorinw resistance yet as only used it half a dozen times. So far its fab but time will tell. Was thrilled to bits - - having a large bust i can very rarely get a costume that keeps my boobs where i want to keep them and I also did expect to have to paint myself into this size 16 but its a fabulous fit and gives lots of support. I know where to come next time.

Aquafit swimsuit

A bit more frumpy than I thought it was going to be. If I had tried it on in a shop I would not have bought it. Not worth the expense.

Swimsuit that delivers

Very happy with my purchase, returned back to swimming 8 months ago with a swimming dress. Which started to grow longer and longer. Each time I finished my swim. Other new swim dress failed to deliver. With my bust raised far to much. However, Decathlon one piece swimsuit Mary - blue and size 26. Was a surprise, at first the swimsuit looked and felt heavy and large. I usually wear size 24, but problems with size 24 swimsuits dress and always go up a size. The straps line could be a little tight. However, my swim turned out wonderful, the straps did not fall from my shoulders and even with my large thighs I felt great. Going to purchase if in stock black swimsuit size 24. This is my own view and I would recommend.

Top notch for aqua aerobics

Absolute joy to wear, I chose a larger size than I would normally purchase as I need to do some quick changes. Having adjustable straps meant that the extra did not make it loose. The fabric felt good to the touch and allowed free movement. It has dried pretty quickly without being spun.

Perfect costume for aqua fit

Love this costume. It fits perfectly and also covers to my thighs. Perfect for any water sport. Get fit all over and the adjustable straps are great.

Fab swimsuit

Very flattering swimsuit which keeps everything where it should be whilst exercising in the pool. Waiting to see if the other colours come back in stock.

Lovely swimming costume.

Exactly what I needed for swimming. As I am an older adult, the costume is ideal, it covers all I need it to and it feels extremely comfortable to wear. This is the second one in this range that I have purchased (different colours.) The staff at the Decathlon store in Leeds are very helpful, professional, knowledgeable and friendly. Thank you all.

Had to down-size

The size I ordered online was too big on collection, I tried it on in-store and was able to exchange for smaller size. I used the costume mid-week and I am extremely happy with it, therefore, I ordered a second one in a plain green colour, it will be delivered to my home tomorrow.

Why do i need to wear a swimsuit with bust support?

You will be in the water but in a vertical position, your bust is therefore subjected to more impact to a greater or lesser degree, regardless of your body shape or your age.During a session, your breasts will move and bounce and can weigh up to 5 times their original weight. A swimsuit with a built-in bra helps protect your bust from repeated impacts. We have 3 levels of support to choose from, depending on the intensity of your sports practice.

Levels of support according to the intensity of your practice

Light support: suitable for gentle activities with little movement in the water (gentle aquafitness, aquabiking, strength training, aqua yoga, etc.)Moderate support: suitable for dynamic activities with movements in the water (aquafitness, aqua zumba, aqua-boxing, etc.)Enhanced support: suitable for very dynamic activities with lots of repetitions (aqua jump, aqua cross training, etc.)For fuller busts, we recommend choosing a model with enhanced support

What type of bra in the swimsuit?

BUILT-IN BRA WITH REMOVABLE CUPS:The built-in bra with removable cups helps keep breast bouncing to a minimum. You are supported by a lining and a silicone elastic that keeps the bra in place during use.The cups shape the breasts and can be removed at your convenience.

Back shape

U-SHAPED BACK:A U-shaped back makes the swimsuit easy to put on and take off. This is great for larger sizes as it makes it easier to get it over the hips and position the shoulder straps.

Why do aquafitness or aqua aerobics?

Once immersed in the water, the body becomes lighter and all movements become easier, even though the water creates more resistance than air and makes muscles work harder. Your muscles get a more intense workout without you even noticing. Aquafitness also has the added benefit of being a "low-impact" activity.So what are you waiting for? It's good for your body, your heart, your health and your mood!
