The Freedom Kilts Casual Model is the only Contemporary Kilt that has true kilt 'swish'. A 36" waist kilt will have 8.38 yards of fabric.
Still not a full wool, but so close that I have sold them to die-hard wool kilt wearers. Everyone who sees the Casual Model comments on the movement.

As far as durability, you may want to get the Work Weight Fabric. It is the actual Carrhardt. Can't beat that for long wearing and abrasion resistance.
Not as heavy or stiff as a UK, and when washed about 6 times with a half cup of 'Downey' it softens right up. It also keeps it's look very well when ironed or steamed.

Ask some of the X Marks members who have a Freedom Kilt for a butally honest opinion.
