I have worn 13 aand 16oz kilts in the dry but extremely hot southwest (Phoenix) as well as the not as hot but still hot AND highly humid (85-100% humidity) central-southern midwest (Louisville) and I can still say I would rather wear an 8 yard wool kilt than any PV, personally. I have multiple wool 8yd as well as one 6yd (more like 4.5) 16oz wool casual and another 8yd PV, and other than the cuts and fit being a bit different, do not really find them any more comfortable, although they are a wee bit lighter in overall weight, therefore less to carry around (2.5 pounds vs 4 pounds). In my opinion, other than price (PV and casual being somewhat less expensive), that weight factor would be the only reason to consider a casual or PV over a traditional 8yd wool kilt. And IMHO I persoanlly prefer the wool tank.
