The Original Pin-Free Diaper Covers are the practical, dependable alternative to plastic pants. Nikky quality has been known for over 70 years: superior fabrics, triple-stitching for strength, and double-layered construction for durability. Comfort. Breathable, natural fibers let fresh air in to keep baby’s bottom dry. Skin temperature stays regulated and comfortable - no rash. And no rough edges to chafe or pinch. Convenience. Adjustable Velcro closures for a quick, custom fit every time. No awkward pins so diaper changing is safe and simple. Great for little sibling helpers, loved by dads and sitters, too! Nikky Care. Machine wash on warm/gentle cycle. Machine dry on low temperature (line dry the wool). Use mild detergent or soap. Avoid bleaches, borax, softeners, and additives. For longer wear, line dry all covers when you can. How Many Nikkys? Four diaper covers is the bare minimum per size, per day. Six to eight is convenient. You may want a couple in the next size up for double-diapering and to grow into. For budget concerns or just for variety, you may want to supplement your Nikky stock with some of the other fine diaper covers we now offer. The problem with plastic pants. Plastic is waterproof all right, but it traps wetness (and ammonia) on baby's skin. Non-breathable plastics and synthetics create a hot, sticky paradise for bacteria.
