There's the traditional 16 ounce kilting cloth, and the heavier stuff ranging from 18 to 22 ounce traditionally used for Other Ranks kilts in the military.

With the creation of the Royal Regiment of Scotland the wearing of that old-school stuff ceased except for the handful of Pipes & Drums who are still allowed their traditional uniforms ("antecedent dress"). House of Edgar still weaves it but it's only in a very small number of military tartans https://www.houseofedgar.com/product...ental-tartans/

Since you're not talking traditional kilts (I don't know what a "sport hiking kilt" is) I suppose you could buy a wool "travel rug" in Buchanan and have it made into a kilt of sorts. That would be the heaviest-weight kilt ever! https://tartanrugs.com/products/twee...ool-travel-rug

They do weave what they call "heavyweight wool" in Pakistan, seen in the What Price Glory reproduction army kilts. It's not like UK-woven wool at all, with a strange waxy flimsy feel.
