Since I've been spending some time tanning deerskins into buckskin, let's take a look at some of the uses for buckskin the Western trappers had.
Typically it was used for clothing. Shirts, pants and moccasins being most common.

Washington Irving describing the appearance of free trappers:
His gun is lavishly decorated with brass tacks and vermilion, and provided with a fringed cover, occasionally
of buckskin, ornamented here and there with a feather.

Charles Larpenteur describing trappers unloading beaver skins in St. Louis:
in their strange mountain costume — most of
their garments of buckskin and buffalo hide, but all so well greased and worn that it took close
examination to tell what they were made of.

Ruxton describing the general dress of free trappers:
The costume of the trapper is a hunting-shirt of dressed buckskin, ornamented with long fringes; pantaloons of
the same material, and decorated with porcupine-quills and long fringes down the outside of the
leg, a flexible felt hat and moccasins clothe his extremities.

Rufus Sage describing the free trapper's clothes:
His clothes are of buckskin, gaily fringed at the seams with strings of the
same material, cut and made in a fashion peculiar to himself and associates. The deer and buffalo
furnish him the required covering for his feet, which he fabricates at the impulse of want

Antoine Clement, by Alfred Jacob Miller

Well-greased pantaloons are a must on the trapline!

I like the painting, K Snow. He’s handsome and he looks happy
