A early father's day present that my little family picked up for me at the Syysmarkkinat a few weeks back:
The jussipaita is symbolic of the region of Etelä-Pohjanmaa, also known as Southern Ostrobothnia. Depending on whom you ask, the Jussipaita symbolizes the sisu, honesty, integrity, and/or craziness, and legendary bravado of the Southern Ostrobothnian people.
I have a bit of Etelä-Pohjanmaa ancestry (by way of the Dakotas and Minnesota) and therefore feel qualified to wear this shirt with pride. If you don't like it, then perhaps we should step out behind the woodshed for a private chat...
This particular sweater is 100% wool and was manufactured by Nuutisen Kutomo.
