RELEVANT BACKGROUND
The Korean War was fought using largely WW2 equipment. Korean War helmet cloth cover camouflage is the same issue as WW2 camouflage.
The floppy wide-brimmed hat seen in M*A*S*H was issued during WW2, Korea, and then streamlined and made arguably better-looking with "grenade-pin" loops around the base--not originally designed for grenade pins, but popularly used by GIs in Vietnam for holding them when decorating their "boonie hats".
HOW TO BUY
The first writer and I each found 12 listed for sale on eBay just by typing "booney hats" in the search box for All categories. However, your spelling, "boonie hats," turned up 625 for me.
To find what you are actually looking for, however, you need to click Advanced Search. In the first field enter "boonie hats camo" (without any quote-marks) OR "booney hats camo" and for -Exclude these words- enter "vietnam revietnam desert" (again with no quote-marks). Then click Search. On the day of writing I got a better-focused AND more manageable 73 items, with a substantial minority of their pix looking like they may qualify. (I assume any few with "Soviet" in their titles are disqualified, but I wouldn't ignore the Aussie ones--I think the word can refer more to perceived style than actual origin.)
I would suggest that if loopless hats prove scarce, you should communicate with established vendors offering with-loops items. They may also have the older style or know where to get it.
"Trapper Keeper" is a brand name for one particular zipper binder.

The Corps of Discovery, led by Captain Merriwether Lewis and Second Lieutenant William Clark were tasked by President Jefferson with discovering what existed in the newly-acquired Louisiana Purchase, including producing maps.

Lewis and Clark incorrectly recorded her name as Sacagawea, which is how she has been remembered.
