I'm not sure if the weight is before they put the teflon coating on or after (adds a bit of weight to the material). The PV tartans we get can run the gammet from 10.5 oz to 12 oz. That being said... every time we SPECIAL order a tartan, it's on the "heavier" side.

I can't compare our PV to a SWK Acrylic as I don't own one. What I CAN say is that most customers (can't think of 1 that did, come to think of it) don't complain about the weight that wear our Semi Trad in winter. If you have the "cahones" to wear a kilt in winter, the slight difference in weight should not deter you. Bottom line... A PV Semi Trad IS a little lighter than a 13 oz wool 5 yarder kilt. It's also over $100 cheaper. Only YOU can make the decision if it's for you.
