Description Luvs now has up to 12 hours of protection, day and night. Luvs Triple Leakguards absorb quickly to help stop diaper leaks before they happen. But our leak protection doesn't stop there. With Luvs you know when they go, thanks to a wetness indicator that turns blue on contact with wetness. You care what your baby wears, so Luvs diapers are 100% hypoallergenic, made free of parabens and free of latex* (*natural rubber). When it comes to the ultimate diaper protection, these paws uphold the laws.
