I own acrylic, PV and wool tartan kilts now. Each has been important in my "evolution" as a kilt wearer. My Acrylics got me into wearing kilts - but to be honest, I rarely wear them any more. My PV kilts are from Rocky and Kelly - they are great (especially in hot weather) - and for their cost there is nothing like them for fit, finish, and clean-ability. But my wool kilts are a whole other critter. Great swish, almost wrinkle free, and the colors are rich and deep. My 5 yarders are great year round. I wear them almost daily. My one handsewn, 8 yard, 16 oz (tank) is a work of art and deserves to be held for special occasions.

If money were no object, I'd have nothing but wool - but then again I live a cool to cold part of the country. I don't think I'm a kilt snob but I have to admit - I do love 100% wool kilts.
