Expertly crafted from stretchy, buttery soft textiles with a stay-dry liner, these super cute fitted diapers offer superior wetness protection for your baby"s delicate skin. Encased elastic wraps snugly, yet gently, around your baby"s legs and torso to provide the very best protection from leaks. And Thirsties Duo Fab Fitteds are easy to use.

Remember, although you"re not going to want to cover up these adorable, ultrasoft diapers, Thirsties Duo Fab Fitteds are not waterproof on their own. At times when you do need total protection, we recommend pairing your Thirsties Duo Fab Fitted diaper with a Thirsties Diaper Cover or Duo Wrap for the perfect adjustable fit and unstoppable performance. "Why would I consider purchasing a 2-piece system when I can invest in Thirsties Duo Diapers for about the same price?" The answer is simple...a Thirsties Duo Fab Fitted paired with a Thirsties Diaper Cover offers superior leakproof protection! Why? Because fitted cloth diapers offer and additional elasticized barrier around the legs and waist that makes it much tougher for anything to escape beyond the diaper cover.
