Swim Diapers are great for infants and toddlers to wear under their bathing suits.  Both Pampers and Huggies have a swim diaper.  They both have a wide range of sizes, and for the most part they both work the same.

Regular diapers will swell up and absorb the water in the swimming pool.  Swim diapers do not swell in the water.  They come in colorful disigns, and fit well under bathing suits.  They are comfortable because they do not sewll and absorb all the water.  Most public swimming place require infants and toddlers that are still in diapers or pullups to wear a swim diaper.
