Muddly Puddles' Half Zip Polar Fleece is a great warm layer to have on hand when you're out-and-about. It’s perfect for layering underneath, with a wide zippered neck that makes it easier to pull on and off. The soft polar fleece is durable and breathable so they can get as busy as they like in it without getting sweaty and you can fling it in the washing machine and it will come up looking good as new.
