The USAK is going to be a custom made garment, where as SWK is a mass produced garment. Even in the casual line, the difference is AMAZING. I've got 2 USAK Casuals, 1 Semi-Trad, and 1 Premier. The velcro is heavy duty stuff and will stay put regardless of what you are doing. I've worn one running, laying around, you name it. If you want a more traditional look with buckles, jump up to the Semi-Trad.

The 24" Length on the SWK's was a deal breaker for me. Those that Rocky has made for me have all been 25". I've tried two SWK's and sold one, no takers on the second.

*NOTE
I am not talking down on SWK's, for me they just aren't an option and don't fit what I'm looking for in MY kilt wearing.

Cheers


EDIT:
I did just see this on SWK's site:
We offer made-to-measure wool kilts (hand-tailored in Scotland, at prevailing prices) to our customers in the Minneapolis-St. Paul area. Due to the significant expense involved, we generally require measurements to be taken in person for custom-tailored kilts. We can order nearly any tartan. We will soon have additional details on this page.
