  • 10/11/2013 Way too small!

    rating star By Erica V.

    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!

  • 6/28/2013 Cute but fits small

    rating star 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.

  • 2/25/2013 Great swim diaper

    rating star 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.

  • 6/20/2012 Great Swimmer

    rating star By AA

    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.

FINIS is Latin for "The End" or "Finale", and it signifies in the name of this company both the developmental goals that swimmers have and the end that they strive to reach—the finish line. 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.
