What is "karvalakki"

A karvalakki is a cylinder-shaped, furry hat or cap typically worn in parts of Finland and Russia. Finnish TV presenter Hannu Karpo often wore a karvalakki on his show, Karpolla on asiaa.

In Finnish, the expression karvalakkimalli ("furry cap model") means a bare-bones, no-frills model, meaning the cheapest and most basic model that just works and does nothing extra.
