I bought this hat a couple months ago for my 17 month old son and I'm already looking for a replacement.
This hat has shrunk considerably. It's 100% cotton which I like, but it's not preshrunk. I have hand washed it and put it in the washing machine a couple times, but not the dryer. It was a little big when we got it and I'll be lucky if it fits by the end of summer. Further, this is a toddlers hat that is hand wash only. We use a sun hat almost everyday at the beach and park so machine washing is a must.
The velcro "breakaway" chin strap is a joke. I understand that it's a "safety" feature, but they need to improve the velcro considerably. I finally sewed the velcro side of the strap on because my son was constantly pulling the hat off. The top part of the hat is very shallow, so without the strap, the hat wouldn't stay on (even if he didn't pull it off).
What I like...
The brim of the hat is stiff so it doesn't flop in my son's face when it's windy.
The terry cloth band around the inside of the hat is a nice feature (although I also had to sew the top edge down).
Once I sewed the chin strap on, I like that it's not a tie. It has one of those plastic toggle things to adjust the length so my son can't pull it loose like a regular bow.
Overall, this hat is made of quality materials and seems like it would last a couple years, but they need to improve the design and make sure the material is preshrunk.
