In 2003, I wore my MacKenzie to the Enumclaw Highland Games. The kilt is in the military summer weight wool, so, heavier than your normal heavyweight traditional. It still was pretty comfortable even with the temps in the mid-80's. Originally was going to wear my Lennox, which is a 13 oz wool kilt, but stepped in something, so the black KH and docs came off and I decided to do the MacKenzie with off-white KH and running shoes.
