Made for children weighing 22-37 kg who require additional protection during night. Looks and feels like normal underwear and is barely noticeable underneath pyjamas. Keeps dry all night thanks to a super-absorbing core. Libero SleepTight offers outstanding dryness. A multi-layer protection system quickly draws liquid away from the surface of the skin and into the core of the nappy, keeping the child's skin dry. Thin and light feeling, just like underwear.
