Size guide

The size guide should be used as a guide as each child is unique. Also, there are slight sizing differences between brands and between countries. 

Generally we recommend that you measure your child's height and use this as a guideline along with the size guide below rather than just using your child's age to gauge the most suitable size.

Please rest assured should you purchase the wrong size you can return for free for all UK orders.
