SIRIN Team Shirt: SSO '8-1-1'
Our first of hopefully many in the 'SIRIN Team Shirt' series — these shirts commemorate the first issuance of the KxS SSO 'SILENT' Combat Knife to operators of the Ukrainian Special Operations Forces (SSO).
The back of the shirt depicts a Silent knife (serial number "0001") beneath the skull-in-boonie-hat insignia of SSO 1st Company, 1st Battalion, 8th Regiment, the first unit to ever receive the blade. Otherwise known as '8-1-1', this storied company has rapidly deployed to and played a crucial role during some of the most pivotal battles of the war, including those at Bakhmut, Zaporizhzhia, and Kursk.
Additionally, the front left chest area of the shirt features the SIRIN owl insignia with our name in cyrillic ('СІРІН'), as well as the craftsman 'K' mark of the SIlent knife's maker KravaCut.
One of three color ways we're offering, this particular design features dark olive drab ink on soft to the touch light olive textile, made from 100% combed ringspun cotton by Next Level . These shirts have UNISEX sizing of the Amercian standard which is the most common one globally. But if you're feeling unsure on which size to choose, simply consult the size guide here on this page.
