Khaki Balmoral - Split back, WW I pattern The Balmoral Bonnet, which is known as the Tam o'Shanter, originated in 1915, as a replacement for the Glengarry, to be worn by Scottish troops in combat. A khaki wool bonnet comprised of a crown with a tan colored wool Touri (pom-pom) to its center, a body with seams to each side and the rear, bow (or string toes) to the rear.
