  • 1/5/2017 Runs extremely small

    4 Review Stars By Swim mom

    The quality is very nice.   I bought a size 22 for my 5 year old. According to the size chart it should have been a bit big.

      It was way too tight.  He could not wear it so I gave it away.  

      I also bought size 24.  The 24 fits ok. The waist is very short.  I would like the next size up. It is a little snug.  He is wearing it. It is holding up well. My son is on the smaller skinnier side.  Go up a few sizes. Nice suit but runs very small.

    I bought this for my 6 year old.  According to the size chart the size 22 should fit him with a little room to grow.  My son is small so even after reading the reviews, I thought that the size 22 would fit well.  He wore it a few times but each time it left marks on his legs because it was too tight. He couldn't wear it.  I also bought the size 24 to save for when he is bigger.  He has worn the size 24 for a couple of months.  It fits better than the 22 but I feel like it is still a little ttoo snug and the waist is too low.  The quality it good. It dries quickly. My son loves it. It definitely runs extremely small. I recommend purchasing two sizes bigger than the size chart measurements.

    My son wear size 22 in Speedo and TYR brands, so I order a bigger size for future use. However, this one too small even it just can pull up to his knee. Not match with the description. I still need to pay $5 for return shipping.

  • 9/5/2016 Sizing was way off

    2 Review Stars By Ann

    The suit seemed to be of good quality, but the 24 was way too small for my child who wears a 24 in all other suit brands. I had to pay to return it, which is irritating since I ordered the correct size based on other suits my child wears.

  • 7/11/2016 Great jammers!

    5 Review Stars By Astrid

    I bought 3 pairs of these for my 3 boys who swim and they liked them so much I bought several more pairs as back up. I also bought the girl version of this suit(love that one too). Love the color and material and they are holding up great. I bought the same size my boys had in their speedo jammers and they fit just right. The rise is on the lower size but definitely covers everything well. I have two boys that are on the skinnier end and one that is pretty solid. Absolutely recommend.
