Bambuno bath bonnets are currently available in four sizes: newborn, small, medium and large. If in doubt, we recommend going with the age ranges below.



Head circumference: up to 38 cm, approximately birth – 3 months



Head circumference: up to 44 cm, approximately 3-12 months



Head circumference: up to 50 cm, approximately 12 months – 36 months



Head circumference: up to 54 cm, approximately three years upwards

The above sizes will fit most children and babies in the appropriate age range. The bonnets have some stretch and equally a bit of extra ‘space’ does not affect their performance. If you are buying a Bambuno as a gift for a child in the upper range of a size, you may wish to purchase the next size up to get the fullest use of the product. However, if you require an exchange due to sizing we are happy to oblige. You can find further information on our returns and exchanges page.


Larger and Smaller Sizes

Should you require a different size, please contact us directly. We can custom-make Bambunos for smaller than average or even early babies (you will need to provide us either with head circumference, weight, or weight at birth plus weeks old). We can also make Bambunos for older children and even adults. Simply contact us with your requirements (age and gender, or head circumference). Please be aware that custom-made items will take a few more days to arrive with you; we will provide an estimate of delivery time with your order. Your right to refunds  / exchanges are not affected by ordering a custom-made item, but we cannot be held responsible for a subsequent delay should you require a custom-made replacement item.
