  • 4/17/2019 Severely Limits Range of Motion

    2 Review Stars By SwimmerMom

    We bought this suit for our daughter.  She loves the Arena brand and the Flex in particular ...  we thought we would try this one for a change.  BAD choice. It causes very limited arm motion, she added time to her fly and free EVERY time she wore it.  Would NOT recommend this suit.  We are going back to the Flex.

  • 12/3/2017 Best Fitting Tech Suit

    5 Review Stars By Swim Coach

    My daughter wears a size 26 in a Practice suit, which is not that loose on her and I purchased the 22 because she wears a 22 in the Carbon Air. The main reason why we went with a 22 in the Carbon Ultra was because she can put on the Carbon Air on pretty easily after the very first time. Also, the 22 is the smallest size, we could find on the website. She says that it is more compressed around the legs and feels like the material is a lot thicker than the Carbon Air. We tried getting on the Speedo LZR Racer X and she could not get a 24 past her knees. So, we switch to the Arena Carbon line and haven't looked back. We have been really pleased with the Arena Carbon line. I will say when you do find the right size I think Arena is a great pick for girls looking for a more fitted tech suit.
