Only for women with tiny chests

This came up really small and was laughable to try and get my chest into. It was supposed be a women's size 12 but I actually gave it to my 12 year old daughter instead. Please consider the huge variation in chest sizes us women have when making swimsuits and tops Decathlon!

Bañador cómodo con una buena sujeción y a un precio asequible. Talla bien, llevo una 40 de ropa y es la que compré. Lo recomiendo.

Muy cómodo y se seca enseguida!

icon-circle-checkmark verified purchase

Bañador muy cómodo para las clases de aquagym, el pecho no se mueve nada y los tirantes se ajustan muy bien por lo que no se baja cuando realizas los movimientos.

Talla pequeño.

Teniendo muy buena pinta, lo tuve que cambiar porque me quedaba pequeño. Lo peor es que no lo tenían de una talla más.

Your activities: dynamic aquafitness classes

Activities: Aquatonic - Aqua Zumba - Aquajogging - Aqua Tabata - Aqua Step - Aquabiking - Aqua Jump - Aqua Mat - Aquaboxing - Aqua Pole dancing - Aqua drums etc.These activities involve a series of movements at a fast pace that, more often than not, use accessories or equipment. The aim is to enhance strength training and cardio work with the goal of toning your figure.

The built-in bra: an important ally for your bust

During your Aquafitness sessions, you move and jump and this causes your bust to move. Wearing a swimsuit that is suited to Aquafitness activities provides you with the support and comfort your bust needs. The built-in bra of the Lou 1-piece swimsuit shorty will support your bust thanks to a stretchy mesh lining and a silicone-coated elastic band.

Crossed back straps

The crossed back and the band that goes all the way around the back help to provide good support. The crossed straps offer a good fit for your body and ensure the shoulder blades are completely free. This cut frees your shoulders to allow supple movements, without the distraction of moving straps.
