All available size guides are displayed on the item page above the Add to Cart button.
Unfortunately, we don’t have more information than what is displayed on the product page.
It is not possible for us to find the right size according to your weight, or your height, or your age (children's sizes). Therefore, we suggest that you take the sizes you are used to.
If the size you receive does not fit, you have the right to exchange/return the item. How to make a return?
