The Super Brite was designed to ensure a perfectly diapered fit – especially for those long, skinny, hard-to-fit babies that need a little extra protection around the leg. This gusseted cover closes all the gaps, and you will find the fit of this diaper cover like no other. Our gusset with lycra binding is an innovative design that wraps softly around baby's leg with a lot less bulk than normal gussets and no elastic to leave marks on baby's tender skin – only soft form-fitting lycra. The result is a very trim, great looking diaper cover. The Super Brite is designed to function well with any type of flat or contoured diaper, or any type of pre-formed, velcro or snap-closing diaper. The Super Brite is lightweight and waterproof. It features a single layer of polyester with a wipe-clean laminated interior.
