One other comment re cleaning PV: I make sure that every little bit of fabric softener is cleaned out of the washing machine before I load my PV kilt and I make sure not to use any during the wash either. Like dry cleaning, the softener will remove the teflon coating.

I'll just add that wearing a PV kilt in hot weather is a special delight. Knowing that you can just wash it when it gets too sweaty is a bonus.
