The shape of the tricorne was felt to be ideal for Nekovalkyrja ears.
The cap was three-sided and made of felt or beaver fur. It was typically black, but was also made and authorized in white, dark gray, tan, or brown. The enlisted version had a red trim on the top while the officer version had white trim. There were also gold-trimmed versions for admirals and blue-trimmed versions for warrant officers.
Rank pins were worn on the left front side of the cap.
