No idea. It’s adjustable. The pith helmet, that is.
So I’ve heard… 
Seconded!
And affect a “Churman Akzent” und dey vill follow Dich Enny-vere!
Ich garantie es!
Der Quas’
I’m kidding, of course, ja?
Only if worn with Jams.
When I lived in St. Pete, Florida, lo these many years ago, the postal carriers in my neighborhood wore pith helmets. The streets were too narrow for them to ride in mailcars, so they walked or rode bikes. I’d imagine they did it because they kept cooler that way, rather than for looks.
OK…
No, they’re just taking the pith.
Former letter carrier here. Our helmets were actually plastic, but they worked pretty well once they changed them to white from dark blue-grey. The broad brim shades you, the shell reflects sunlight and the suspension leaves space for air to circulate. There was also a version molded from some sort of open-weave coarse fabric which didn’t work so well.
Wore this in Death Valley last year, worked great.
Silenus has a photo of me wearing mine in Palm Springs. I don’t hit the desert without it.

That guy in the Brit pattern looks like he just got caught boppin’ his baloney.
But, yeah, I prefer the British pattern.
Along with a safari shirt and 6" inseam shorts. Both khaki of course.
As an added accessory, one of those multiple pocket vests.
I have all those exept for the helmet.
Q
PS: He also needs to lose the beard. That thing looks like pasted on pubic hair!
Word.
I have two of those vests-of-many-pockets. One in olive and one in black. The black one is very handy for when I feel like dressing as a space pirate.
I also have two of those vests-of-many-pockets. Very useful when I’m working on a film. (And that’s what they’re made for.) One has stow-able straps that go around the knees so that a cameraman can sit on the ground stably and comfortably. 
I don’t have a pith helmet or a safari shirt. My khaki shorts are the REI hiking trousers with the zip-off legs. (I do have a pair of OD shorts I made from having the legs cut off a pair of BDUs and having them hemmed.)
The British still wear the current version of the “Wolseley” in the dress uniform of the Royal Marines, obvioulsy flatter (and better suited to sun protection) than the Boer War high-crown vesion (which was a pith version of the stiff felt home service helmet
The French initially wore high-crown helmets, but they too switched to a broad, flat version out of practicality. This design was kept by their sucessors, the NVA
The Krauts had a few versions of their own, in the old empire, and when they were Nazis as did their snazzy Italian allies
The WHO?
:D:D:D:D
I’m just kidding, of course!
I’m proud to be half “Kraut” and I like the “East African” issued one!
Great educational post, ST!
Makes we wanna find one on one of the Army Surplus sites!
[minor hijack] I have been searching forever for a desert flight suit from the WWII/Korean war era!
I have my original No-Mex one from my Zoomie days (OD), but not that one!
Had one once, but it had too many holes to patch anymore! [/minor hijack]

Look here. Three ‘exact reproductions’.
You can get your CWU-27/P in khaki Nomex from here. I can recommend this company; both for their products, and their customer service.
This one is a poly/cotton replica of a CWU-27/P. Not WWII/Korea, and not Nomex; but it’s only $35.
With what’s been going on with me lately I couldn’t be that frivolous, Johnny, but I bookmarked those sites for better times!
Those “higher priced” ones are some that I saw on a rack for 5 bucks in the 80’s, and they looked cool as hell!
Jump suits are great when you don’t wanna “dress up” and look like an “International Male” fashion model!
Just brush your teeth, take care of the “pits” and throw some mousse on the head and you’re set to go!
(Not on a date, of course!)
Q
I only wore mine when I was in the CAP (required when flying a CAP aircraft), and for Halloween. Very comfortable… But not so much fun when you have to defecate.
Waitaminnit!
Surely you added a “rear-end zipper” in yours, John?
J/K!
I know: You had to bring that whole upper part down below your knees, right?
Q
(Man said “defecate”. Didn’t say “shit”! How we gonna “score” that here on The Dope?
