Keep kids comfy and cosy this winter in the base layer thermal bottoms from Muddy Puddles. Crafted from a premium blend of cotton, polyester and Spandex, these bottoms offer exceptional comfort, while their brushed interior is irresistibly soft on delicate skin. Magic moisture-wicking and breathable fabric ensures growing explorers stay comfortable and dry, even after a wild day of active outdoor play. Ideal for layering under ski wear or waterproof trousers during chilly outdoor adventures, children can wear these multipurpose bottoms across the seasons. Pair them with the matching base layer top and hey presto - a delightfully snug set of pyjamas! Our base layers are machine washable at 30 degrees, making them easy to care for, built to last and - as we always encourage - designed to be passed onto someone smaller once outgrown!
