love this swim diaper . we use cloth diaper normally , so do not want to use disposable swim diaper . we daughter go to swim class at the y so be swim all year round . in the previous size , I buy the only reusable swim diaper available locally but it pull on and off like underwear . it contain the accident fine , but my husband really do not like try to change she after , which could get messy . so , I order this one because it velcro like a diaper to make change messy diaper easier . she have not actually stool in this diaper since we get it , so I can not be certain how well it would work for it be intended purpose . however , it do fit well and seem comfortable for she . it be also very cute . it do not hold urine , but no swim diaper -lrb- even the disposable -rrb- do .
