Sienna Cap.

This style features an adjustable strap at the back.

Every child has their own head circumference, regardless of age. The best indicator for choosing their size is therefore the head circumference (in cm). Please refer to the information below:

• Size 9–18 months: head circumference between 44 and 48 cm.
• Size 2–5 years: head circumference between 48 and 52 cm.
• Size 6+: head circumference between 52 and 56 cm.

To help you measure their head circumference, it's here.

If your child is between two sizes (or on the borderline), we recommend going up a size. If you have any doubts, we're always here for you: hello@hello-hossy.com.

Two sizes are available:
