Sisu is a unique concept in Finland. It stands for the philosophy that what must be done will be done, regardless of what it takes.
Its history goes back to time when Finns were obliged to struggle against harsh nature and foreign intruders. Despite all of the drawbacks along the way, the struggle gave a lot of strength.
Sisu is a special strength and persistent determination, a combination of stamina, perseverance and courage.
Sisu is what we Finns are all about.
