Size Guide

Kids will enjoy their autumn and winter adventures even more when they wear these high-quality Muddy Puddles Drift baselayer bottoms. Comfort and cosiness start with warm layers, and that’s why wearing a base layer is such a practical choice for growing adventurers.
Designed to keep young explorers of all ages feeling comfortable and cosy whatever the season, these bottoms are made from a warm and soft high-quality fabric that is impressively breathable and boasts outstanding moisture wicking capabilities so that even the most adventurous little one won’t overheat as they run about in the great outdoors.
The perfect choice for layering under waterproof trousers for an additional layer of warmth on the coldest days, these baselayer bottoms can also be worn alone with the matching Drift baselayer top as the cosiest pyjamas for lounging about. As an added advantage they’re also machine washable at 30 degrees for greater convenience.
Made from a high-quality fabric blend of 35% cotton and 60% polyester, these bottoms also have 5% added Spandex so they stretch perfectly and fit to your little one’s body even more comfortably. The brushed interior is also soft and gentle on kids’ skin so there’ll be no unwanted itching or discomfort.
Thanks to their unisex navy colour, these baselayer bottoms can be worn by boys and girls alike, and as they’re durable and long-lasting, they can easily be passed down to younger siblings, friends, or family members for many more fun all-weather adventures!

Shoe Size Conversion 

All our wellies and snowboots are true to size but if you want to wear with thick socks try a size up for comfy fit. We also suggest a size up in our Puddlestomper wellies as they can be a little narrow.
