I gave mine away a long time ago. For a casual kilt, USAK casuals cannot be beat. Sportkilts, after a handful of washings, just end up looking like you've wrapped a tartan bedsheet around your waist.

If they are using poly-v now, then it would be a great improvement. That being said, after owning both, I much prefer USAK Casuals.

If price is a consideration, Stillwater Kilts are great, I keep one in my closet for friends to wear to kilt nights and concerts. I'm just not a fan of acrylic anymore.
