Yes of course! Waxed cotton is an amazing fabric that whilst being waterproof, is also breathable, unlike plastic fabrics. The fabric adjusts to the temperature, keeping your little one cooler in the summer and warmer in the winter. Waxed cotton softens as it’s worn, keeping your little one free to move around comfortably as they please! Our waxed cotton is made using natural materials. Our coveralls are washable. After repeated washing, when the time comes to top up the waterproof protection you can easily re-proof your coverall using Nana’s Manners Original Wax Reproofing Spray This simply replaces any natural waxes they may have worn done from repeated cleaning, bringing your Coverall Bib back to tip top waterproof condition! Made to last for years to come.
