My first kilt was a 20oz Canadian Army surplus kilt (Black Watch of Canada), and it was a HORSE BLANKET, but with good reason -- the military has to make 'em that sturdy to withstand the rigours of soldiering, and to last from squaddie to squaddie. It was murder in the summer here in SW Missouri.

My Hector Russell kilt is 13oz, and it is comfortable for both summer and winter.

Cheers!
