I have a couple of pairs of the suede Barnstable chaps, off the rack, not their semi-customs, one is probably 12 years old and still in good shape.
They are pretty nice, decent leather, heavy duty zippers. Comfortable and wear like iron. Ovation makes some off the rack chaps, but they are not nearly as nice as the Barnstables…thin leather and don’t fit very well. I have seen the top grain Barnstables in the Smartpak sale loft, but didn’t really like the leather…thinner and stiffer than the suede.
Barnstable is very easy to work with, I was considering ordering some semi-customs last year (their small fits me very well, except they are bit short)…my calves are actually two slightly different sizes, I called them and they told me I could have two different width legs (small calf on one, xsmall calf on the other) for only $10 more. Plus, I like giving my business to a local company when possible ;).
Do get them tight, like tall boots, just barely able to get the zipper up, as they stretch faily quickly.
