Not a one size fits all hat

This hat not one size fits all.  It really medium size hat that is tight on my head.  I'm hoping the hat will stretch a little to make it more comfortable.  Other than that, the is a good quality hat.

Hat is kind of big. I had several people try it on to see if it was just me but it didn't fit them well either. Wasn't worth spending the money to return it.

this hat came in size S/M. I assumed it would be kind of a one size fits all. So we like it, but it is way too small. I wonder how we can get a XL one?

Able to fit heads of all sizes and comfortable to wear. However I didn't expect the front part of the hat to be as big as it is. It looked like the hat did not fit and was towering on my head.

It says one size fits all but that is not the case. If you have a bigger than average head, I wouldn't buy this hat.

Nice hat but definitely not one size fits all. I'm close to a size 8 and there was no chance this is ever going to fit on my head. I did some searching for big headed people like myself and found several sites that separate their cycling caps into small/medium/large/x-large. I ordered a few from Walz Caps and like them a lot, they have a huge selection too.

Great hat, but is one size fits all, not adjustable. Fits up through a size L, only.

This hat runs VERY small and did not fit. "One Size Fits All" is not an accurate description, I definitely do not have a "larger than normal" head either. Will be returning.

This a nice hat, however it is definitely not as big as I expected. I have puffy, curly hair and this hat just wasn't going to work. Also, the brim isn't as wide as I would've liked.

The hat is large, but I have a small head.  It is adjustable though and will work fine.  It's not as comfortable as some of the more expensive ones I've tried.  It is attractive on and I'm glad of that.

It's adjustable but the hat almost swallows my head. Normally baseball caps are the only hats big enough to fit my head so it was odd when I put this one on and it covers by ears. Someone mentioned they washed theirs to shrink. I will have to give that a try.

It was quite large for my head and I needed to return it. Definitely not a "one size fits all"

Absolutely not a 1 size fits all!! Im a 7 3/4 (I know big head)  but I don't mind hats looking smaller on me... but this? Its ridiculously small...

I purposefully bought this hat as others said it runs big, and my bigger nugget can never find a sun hat as they are all One size fits most. The hat is great, but is was too small for my head. I ended up cutting the inner band in a few places, allowing it to stratch out a bit, so I will keep it. I have no other choice as I have not been able to find sun hats that come in different sizes. Hat companies take note, people are different, and everyone needs sun protection!

I love hats but sometimes they can fit a bit large, this is an item you need to have on hand.  You can adapt to your size.  I cut mine in half and was able to use this one order for two hats.

Nice looking hat -  but back/cap part way too large for most normal heads. Tried on a few people. I have to fold it under to make it fit..

Seems like a nice hat for the price.  However, be wary if you have a large head. It does not fit comfortably.
