Trusty Trunks
Leak-Proof Swim Diaper
Product Design,

TrustyTrunks diaper covers are made of a very elastic, non-allergenic material that is soft on your child's skin. They are worn over your child's regular diaper, providing a consistent feel. The tapered waist and leg designs allow you to cut material off, making the openings wider so the openings are tight enough to seal, but not too tight. Several months human factors research went into testing and creating four streamlined sizes.
Cryptosporidium is a chlorine-resistant protozoan parasite responsible for the majority of waterborne disease outbreaks in recreational water venues in the USA...Improved swim diaper solutions are necessary to efficiently retain pathogens and effectively safeguard public healthNCBI
Swim diapers can delay diarrhea-causing germs, like Cryptosporidium, from leaking into the water for a few minutes, but swim diapers do not keep these germs from contaminating the waterCDC
