    Tween Comfort

    I ordered this for my tween who is on a swim team. She has loved using the suit as it gives her confidence in the pool that she will not leak. She likes the thicker straps of the sport style suit. Will definitely buy more as she grows. She fell in between two sizes (S & M) the S has less gap area around her hips and bottom.

    Superbe maillot

    Le maillot est parfait, il est très utile lorsque ma fille a de la natation pendant ses règles. Jusqu’à présent elle est très satisfaite! De plus il lui va très bien et on ne voit pas de différence avec un maillot d’entraînement habituel.
