From the web site at buzzkidder.com:

"Inspired by the khaki kilts issued to the Tenth Battalion Black Watch Regimen during WWI, Buzz Kidder's Celtic Shoppe created the Canvas Kilt, a popular
and practical alternative to a tartan kilt. The 10-oz. Army duck canvas kilt is sewn in the traditional style, with handmade pleats that are fully machine-stitched
for easy maintenance and durability."


First, I had to read that carefully; it does not say that the original khaki kilts were canvas or cotton.
I'm not finding much information about these khaki kilts, but they are mentioned on a few sites. I'm assuming that the Tenth Battalion Black Watch Regimen members were, in fact, issued these khaki kilts during WWI, as stated.

Were these kilts made of wool?
Were they made just as a traditional, eight yard, military kilt is constructed?
Or is the khaki kilt just a myth?

Thank you.
