  • 9/10/2017 Not absorbent

    It is not made absorbent enough.  My son peed and it didn't absorb it at all.

    I bought this for my 28lb daughter who will soon be 3. Using the size chart provided I ordered the X Large. It was entirely too small!

  • 8/12/2017 European style

    4 Review Stars By Angela C

    We ordered these in blue for my son. They are cute but I gotta say they are cut "European" style if you catch my drift! They work but the legs are cut a bit higher than the others we ordered. My husband calls them super speedo style.

  • 6/28/2013 Cute but fits small

    3 Review Stars By J''s Mom

    My son weighs 30 lbs but I decided I didn't want to get one too tight so I got him the XX Large (fits 33-38 lbs). It STILL feels too snug on him. It's so tight it's hard to get them on and off of him. I know they are supposed to be a little snug so nothing leaks out, but these seem to be too tight.  I love the idea of this swim diaper but the sizes are way off.

  • 7/29/2017 Swim Diaper

    4 Review Stars By Lupe

    I ordered the largest size swim diaper available, a 4T, because my daughter's new swim school requires her to double up until she is 4 years old. She has a few months to go till then but she is already wearing a kids size 6. The diapers are good and they fit her very snug but they have enough stretch in them to work. I would recommend them for kids that actually do wear a 4T. If you have a similar situation to me and your child needs a swim diaper in a size they do not come in I would recommend something with a side snap for easier on & off.

    5 Review Stars By Girlmom

    This swim diaper fits perfectly and is comfy and cute! I still used a disposable swim diaper under this, but it worked great. I will definitely be purchasing more. The colors are also very bright and have not faded.

  • 2/25/2013 Great swim diaper

    5 Review Stars By Ian

    Used for our 20 month old son in the chlorine pool and in the ocean for our trip to Hawaii.The fit was great, and the elastic is stretchy enough to get on easily, but tight enough to stay on until you want it to come off. He usually wears some swim shorts over the top, but the green is a great color, so it can stand alone.

    He is 20 months old, and around 25 pounds, and the 18-24 months size fits perfectly.

  • 7/9/2017 Great Purchase

    3 Review Stars By Chelle

    Love the water shoes, thermal suit and swim diaper.  This is our second year of purchasing this thermal suit. My daughter prefers to wear swim pants under her swimsuit. These are a bit small and she is quite tiny. However they will work for this year. Maybe next year she will grow out of wanting to wear bottoms under her swim suit.

    Great quality swimmer. My son's old pair were not even close to the quality that these briefs have. Sized a tad under but still worked for my son.

Founded in 1993, FINIS provides highly technical competition suits, training equipment, child water-safety products and high end goggles. Their very popular SwiMP3 water-proof digital media player is revolutionary in its streamlined design, enabling a swimmer to listen to music while practicing laps and other exercises in the pool.
