Here in Finland we have this time of year a season sale, so you can find brand gear -50% -70% discount. Unfortunately Rukka is often out of these campaigns and max discount of Rukka is often ~20% ( although it's a domestic brand). I'm planning to buy new Gore Tex jacket+ trousers, so I have visited several shops in southern Finland. To give some examples of prices now, a set of Scott 390 eur, IXS Pathfinder 400 eur, Rukka Steel 600 eur, Rukka Adventure 1050 eur.
I have travelled several times in Baltic countries, I know there are some shops selling mc supplies, but quite often they dont have goods in stock. So if you want to get clothes at once, this may be a problem.
If you want to get names and addresses of local shops, or if you need some other support during your visit in Finland, you can send me private mail.
Best regards, have a nice ride and be awake in Russia, Baltics and especially in Poland. They are nice countries, people are very friendly, but traffic is wild.
