I've thrown my PV kilts (semi trad and Casual) in the wash several hundred times and they haven't pilled yet. How old is your PV kilt? What tartan is it? If it's the Maple Leaf (or any "canadian tartan"), it's not made by the same company that does the "Low Pill™ fibre technology" thing that we use. MM is the only mill (to my knowledge) that does the Teflon or "anti pill" thing. There are several other mills that WEAVE PV, but DON'T coat it in Teflon or do the anit pill thingie. If it WAS MM that made the fabric, was it before (since the kilt is 3.5 yrs old) they started doing the Low Pill™ fibre technology thing?

Not sure whose kilt you're referring to about the velcro "stretching" throughout the day, but that's one complaint I can honestly say I've never heard before. Maybe the velcro isn't as "strong" as it should be.
