This glengarry has the 48th Highlander cap badge and was worn by the 15th Battalion (48th Highlanders) the first of three battalions of 48th raised by the 48th Highlanders.

The Glengarry bonnet is a traditional Scots cap made of thick-milled woollen material, decorated with a toorie on top, frequently a rosette cockade on the left side, and ribbons hanging behind. It is normally worn as part of Scottish military or civilian Highland dress, either formal or informal, as an alternative to the Balmoral bonnet or Tam o’ Shanter.
