I have no problem recommending Skye Highland Outfitters for casual PV kilts or their 8 yard traditional style PV kilt. I own both and they are well made and a good value. Another option for to look at is forum advertiser Alt.Kilt I have heavy weight twill kilts with cargo pockets that are great for more active going. I have dogs and we like to roll around in the park and these are great for that.
I also like these for travel as in and out of planes, trains and automobiles it easy to spill or get stained and they wash well. That is not to say PV does not, but I just avoid getting then unnecessarily dirty. I would be bummed getting my PV tartans soiled.

It would never be my intention to "slam" a vendor but I saw an earlier reference to AmeriKilt. I would do your homework here. I had real difficulties with how easily they wrinkled, literally right after pressing. Additionally for your hot humid days they are fine but cooler temps would be more challenging.
