This suit is great. It matches with the speedo quality guerentee. I can always trust speedo with the great quality they put out. I wear this suit in all practices and meets and have for the past year and it still fits great. NO strech or cut. The bottoms arent fading out like they do on other suits also. 78 % Nylon, 22 % Spandex Imported Made with 78 % Econyl, a nylon fabric made from 100 % regenerated nylon from pre and post - consumer waste. Retains its shape up to 10 X longer than traditional swimwear fabrics Offers 4 X the compression of standard fabrics and is twice as stron 30 percent more resistant to fiber breakage in chlorine compared to power flex Good for the environment, even better for swimmers. I recomend this suit to all people that I can and hope this can take me far in my swim career. Read more
Fit is good, however after 2 months they are COMPLETELY faded. Bought black and they are now a light gray. At the back seam the material is so faded it almost looks see thru. Need to buy another / different pair before a swim meet in 5 days. UPDATE - they are actually see thru at the back seam, not faded. To my horror I noticed it while my son was swimming!!! Absolutely awful. How embarrassing for him. If I could give zero stars I would. I want my money back. Read more
Perfect fit. My little swimmer loves them. Read more
I already have another pair of size 22s from a different brand. I purchased these in the same size and they are WAY smaller (see picture). They are way too small for my small to average sized 5 year old. I sized up to a 24, and even these were smaller than the other 22s I own. Yes, this still is supposed to be snug, but these were beyond snug! Definitely size up!! The quality otherwise seems good and the color is vibrant blue. As an aside, amazon kept telling me I was buying women’s or men’s or a different color so don’t be alarmed if you get the same notification! The correct item/color/size arrived! Read more

I’ve been using it for the entire swim season this year and it hasn’t been giving me any problems. Read more
I wish there was just a regular S/M/L sizing to this but I read reviews and bought what I thought was going to work. My son is 8 but he wears a size 10 in clothes because he is so tall but very slim. When I buy size 10, the length fits but the waist does not. I bought a size 28 in these and they fit him perfectly! I believe the fit on these would equate to a size 8 in boys. Read more
Hands down that Speedo has one of the best quality swimsuits out there. My problem is the sizing chart, which is very imprecise. Our 8 yr old is very skinny, yet the jammer we bought fits too tight on him (yes, we are aware that the tight fit helps with competitive swimming, but this sizing was very wrong). It was ok for the concluded training season, but will need to buy a new pair for the next year..... Read more
