The gymnastyorka (till 1917 officially named "gymnastic tunic", гимнастическая рубаха) was originally introduced into the Imperial Russian Army in about 1870 for wear by regiments stationed in Turkestan during the hot summers.
Originally intended as a working dress during peacetime and patterned on the traditional Russian peasant smock, the gymnastyorka was subsequently adopted for ordinary duties and active service wear.
[2] During the Russo-Japanese War of 1904–1905 the white gymnastyorka with its red or blue shoulder-boards proved too conspicuous against modern weaponry and the garments were often dyed various shades of khaki.
[3] The smartness and comfort of the white gymnastyorka enabled it to survive for a few more years of peacetime wear until a light khaki version was adopted in 1907-09 and worn during World War I.
After the Russian Revolution of 1917, a new version of the gymnastyorka with a stand-and-fall collar was issued to the Bolshevik forces, with three razgovory straps sown across the chest in branch colours.
