LaphroaigQCFan,

I know that you said "for lounging around at home," but I have to submit that's my SportKilt's best role. In a sense it's my "most worn" kilt, since I put it on every morning. When I'm out and about, the USAK semi-trad is my most worn. The casual is great for traveling (airports especially---no metal).
