Our Kai swim pants have a triple layer and therefore can be used as swim diapers. They have a two buttons closure on the side. The fabric is UPF 50+ sun protective and made out of eco friendly fabric, using ECONYL®, a 100% regenerated nylon fibre made from recovered fishing nets and other nylon waste.
The kids sizes go by years. The Kai swim pants run rather big. If you are not sure about the size, we are happy to help.
