    Suit was used for first LC meet of season when I was not ready to wear my LZR.  Like the cut of the suit, needed one size bigger

    Good suit, but way too much room in the butt area.

    I am 5ft 3in 115lbs and ordered a size 26 in this suit. (I wear size 28 or 30 in a practice suit). I recommend buying a 1 size lower in this suit because it's a racing suit an because the fabric stretches easily.

    This isnt that best fabric/technology Arena has to offer but it is good to use for meets during the regular season.

    The cut of the back is bigger than normal lingerie cut practice suits and the cut on the butt area is rather small (i.e small wedgie when doing a start) but still provides good coverage.

    The seams feel very strong and held my body shape well.

    There is no beading technology in this suit or if there is it wasnt very obvious but you can tell that this suit does repel water.

    I have used this suit a total of 5 times and the fabric has not ruined yet and still repels water, however, these last couple of times may be my last that I use this suit because it will soon stretch out and wont be very efficient.

    I had also bought this suit for only $50 on a different site and the site gave me two even though I only paid for one

    Overall, this suit is good to wear during regular season meets but I do not recommend it for championship meets. If worn in champ meets i recommend to wear only during prelims.

    Feels too big

    This is a nice suit for day to day meets. It runs much bigger than the carbon pro line and we had to order a second in a smaller size. My daughters are 5'8" and about 140 & 145. The 30 carbon pro knee skins are very, very tight. We wear these for regular meets but a 28 is still generous. This is a great value for a day to day meet suit.

    Arena makes such great tech suits. People just need to know that they run SO much smaller than Speedo, but my girls like them so much more. My girls race in 30 Arena Carbon Pro, where they wore 24L Speedo Knee skins. Both are 5'8 and about 135#. These are just regular meet suits for us and a great price for weekend to weekend meets.

    Feels too small

    Was looking for a fast suit with thicker fabric and tighter fit / better longevity than an aquablade.  The fabric was nice and fit on top was good.  However, the back opening is quite large and the rear of suit was skimpy.
