Nothing to really add, except that I own one and didn't realise it was machine washable.

I have succesfully machine washed my SportKilt, which also has to be done on the gentle cycle, and has to be drip dried, as it cannot be machine dried. I wonder whether it would also work to hang up my Thrifty to dry it - don't see why not? I don't put my SportKilt in a mesh bag, as they don't mention doing that in their washing instructions.

The big question is which of my other kilts I could machine wash on gentle and then drip dry on hangers? Several of them are acryllic. The SportKilt actually isn't. It's a polyester blend of some undisclosed variety.

What about the ones with leather straps and metal buckles? I just realised that the Thrifty Kilt and the Sport Kilt both use Velcro. Maybe that is why you can machine wash them?
