Nabadi is a coat made from felt or karakul (the short curly fur of young lambs of the breed of that name).
Karakul being quite expensive, burkas were usually sewn from felt treated to look like karakul. Nabadi are sewn with high, squared off shoulders, and wearers will have a distinctive high-shouldered silhouette.
Nabadi were part of the customary male garb of various peoples inhabiting the Caucasus region. Nabadi were adopted by Russian cavalry, and worn as part of the Russian military uniform from the middle of the 18th century until the 1850s, during the Caucasus War.
