The hat is lightweight but not see though so it's cool and great sun protection. It's a very nice fabric that’s lightweight and breathable. This hat is so cute and super adjustable.

This hat fits perfect.

It cinches around the brim and under her chin, love it. Sun protection is so important when you are fair skinned.

It fits great. The straps allow it to be adjustable so it's a great fit. Generous width brim for protection from sun.

The cinch around the head is tightened to fit and has a lot of room to grow. It adjusts under the chin and around the circumference of the head. The chin strap is adjustable so my baby has worn it comfortably for 13 months so far.

Hat is too big on my 8 month old (20 lbs, head circumference 43. Inches) the brim is too floppy and constantly hangs over the babies eyes. Very cheap buckle.
