If you are wanting a tartan... MartonMills p/v is your best bet.. but if you can wear solids, well I believe MM is an option, but other kiltmakers use a poly blend, that looks good too.. check out Freedom kilts, Steve has some nice kilt
options.

I know we have member of the forum, who have issues with wool.. one in particular, his wife is allergic to wool. I believe there are many options, to keep our fellow kilters, enjoying the lifestyle, we all enjoy.
