Wrap | Size 2 | ChecksLittlelamb wraps are made from a naturally stretchy and soft knitted poly fabric that has a breathable membrane bonded to the inside. This ensures air can circulate through the fabric, keeping the temperature down, but the larger moisture molecules are kept inside. The result is a wrap that keeps the wee and poop contained. The wraps were designed to fit around our shaped nappies perfectly but they also fit most other brands of shaped and flat nappies
