I love these hats! I'm one of the people with a small head and regular hats don't fit. This one is slightly bigger(size large) than my old one, which was one size, but it still fits well. I like that this is a child size but the brim is still large enough to cover my adult sized face.

Sooo…I’m a 76 year old woman with a very small “raisin” head. ☺️ These hats in a kids’ large fit me perfectly. I love the light weight and adjustable strap.

Great hat for kids!

My girls aged 7 and 9 love these hats. They great quality. Super cute and sporty for when they don’t want to wear a full brim sun hat.

Fantastic! More Colors Please!

Purchased 4 for my 2 kids who play tennis. Keeps their head cool and sunburnt-free. PLEASE come out with more different colors!! Would love a black and/or white for easier outfit matching.

Best Hat - Nice Colors

I am one of the ladies that have a small head. The Kids size large fits me very well. I walk daily and it block the sun perfectly.

Good for small adult heads.

I have a small head and this kid's hat in size large fits great and looks great and has a nice long brim.I pair it up with Sunday Afternoon's Solar Curtain neck gaiter on really sunny days, wear it under my jacket hood on rainy days, and for extra warmth I pull my Buff over my head and add the Impulse cap on top. Perfect, versatile hat for me!

Excellent for adults with small heads. Lightweight and low profile. I have two now!

Great cap for small adult heads

I'm an adult lady with a small, 21" head, and I love this hat! I did find that the sizing strip in back kept slipping, but after I sewed that in a fixed position, the hat is perfect. The lightweight material is great and so is the fit around my ears - not too low but not too high, either, despite it being a kid's hat. I especially love the reflective band around the edges; since receiving the hat I've worn it during every one of my evening walks. Please make this hat in other colors!

Impulse cap

As a petite adult (smaller than average head) this hat fits perfectly. Very pleased with my purchase.

Great for Small Adults too!

Great hat for adults who have smaller heads - does not look like a kids hat. Fits my 19.5" noggin perfectly. Any adult hat I try on is much too large, so I've been buying Sunday Afternoons kids hats for running and the beach for years, and just ignore that is for "ages 5-11" or whatever. :). Just ordered this cap in blue as well!

I bought this for my 8 year old who is very sensitive to clothing and accessories that are uncomfortable. Within the first few days she's already worn it to the pool and the beach and kept it on ALL DAY! It's lightweight and dries fast. The adjustable strap helps it fit perfectly and stay on her head. Such a hit that my 5 year old wants one too! Will be ordering another one!!
