My fitted hat size is 7 1/2. The L/XL fit tight but is wearable. Hoping it will stretch out a little bit after wearing it for a while. Starts to hurt head after
 1 hour of wearing. The next size up 2 XL would have been too large.

It's fits!!!  In fitted hats a 7 7/2 fits snug and a 7 5/8 fits a little loose.  Have bought so many sun hats in the past that just don't fit.  Based on the reviews on sizing, I took a chance and bought this and it fits.  Fist close to what a 7 1/2 fitted hat fees like.  Snug, but not too snug to leave marks on your head, but still snug enough to keep it from easily flying off with a gust of wind.

This one is definitely a keeper.  Due to to fact that the hat is made of straw, I don't expect it to last very long, but at this price, I don't mind replacing it every few years.

I ordered a hat that was supposed to be XL/XX and it ended up being M/LG. Needless to say, it doesn't fit....

I wear a 7-1/8 to a 7-1/4 and I find the large a tad loose even with a full head of hair; the hat is great though so I'll probably order another.

I wear a 7-5/8 fitted hat and the XL is too small for me.  I believe it will give me a head ache if I have to wear it for an extended period of time.  Not sure if this has anything to do with the sizes running small, but the product is made in China.
I will most likely be returning this, which is a shame because I like everything else about it.  If only they made a XXL.

I have tried most of the caps in this type of headwear and I think for my head size 7 1/4 it fits me perfect. I have purchased ten caps in different color combinations. Overall I think your fine up to a size 8- 8 1/4,but that is just my estimate.

if you have a big head like me then this kind of hat WILL fit snug and small, i wear a fitted XL and this hat fits kind of small. The quality is OUTSTANDING!

7-5/8 is my normal hat size. I went with the 7-3/4 as recommended and the fit is a little loose but easily snugged up with the chin cord method as shown on the TIlley website.  Looser is much better than the tighter fit I would have had with the true 7.625 I though I needed.

The hat can not fit upon my head. It's not a one size fit all type of hat.

My hat size is 7-1/2. I ordered the XL size, and it is -just- a tiny bit too tight. Wearable, but doesn't stay on securely. The leather is quite heavy (which is good), but that also makes it unlikely to stretch easily to achieve a better fit. Very nice hat, just be aware of sizing when ordering.

Cute, but according to my measurements (58cm) I should well over be a L/Xl. Mind you, I might have done these wrong since I feel I have a small head. I will be returning and purchasing size down. However, the only two sizes are S/M and L/XL so I am a little worried neither will fit...

This is a well made hat that is true to size. My head measures right between a 7 3/4 and 7 7/8 hat size. The Henschel size chart shows that the XL is for hat sizes 7 1/2 to 7 3/4. Based on so many reviews indicating that the hats ran large, I tried the XL. I was able to get it on, but it was a bit too tight. To me this indicates that their sizing is dead on. My only actual gripe is Henschel's use of very similar model numbers for their different variations. I'd been looking for a crushable/packable hat, and I really thought I was ordering one. As it turned out, this is the 5320, which is not crushable. I made sure to get an XXL 5220, which is the crushable version of the same hat.

Hat is extremely well made.  I bought the L/XL and it was way too large for me and I am a 6 foot 210 pound man.  Returned it for the M/L but has not yet arrived.

If it wasn't for the size, I would say it's a 4 or 5 star rating. However, my head size 7-1/8 fits within the size stated but it's rather tight unless I wear the hat back on my head.
