Hi Dave,

I really like my USA Casual (Scottish National tartan). One difference nobody has mentioned yet is the Casual comes with belt loops for a 1.5 inch belt. So, you can wear a regular belt instead of having to buy a kilt belt. Furthermore, Rocky will provide wider belt loops upon request. USAK will have an Irish National pv tartan soon.

I don't have a Stillwater kilt yet, but I will probably be getting a 2006 Nightstalker in the near future now that the pleats are being sewn down at the hip.

The big difference is a USAK is a custom made kilt (you get exactly what you want) and a Stillwater is an off the rack kilt with no options.
