The thermal base layer top from Muddy Puddles is a cosy thermal that lets young explorers enjoy outdoor play to the fullest. Made using a premium-quality cotton and polyester blend, the top contains added stretch for greater comfort while the deliciously soft brushed inside feels positively cloud-like on skin. While keeping young explorers warm in the cold, this breathable material switches to keeping them cool when they get hot, wicking away perspiration and keeping them dry after a run around. Another fab feature are the thumbholes in the cuffs. This means sleeves remain firmly in place when layering up over the top. For added versatility, the Muddy Puddles base layer top can be worn solo or with the matching base layer bottom to make a warm and cosy pyjama set, perfect for lounging about on cosy winter days indoors!
