How many clothes should I wear to Finland?

The first thing to look at is luck. Traveling to northern Finland in winter, the weather changes greatly. For example, before we arrived, the local outdoor temperature was MINUS 40 degrees, but during the week from our arrival to the end of my trip 14 days, the temperature was almost the same as that in Beijing in winter, so we can only say that we are very lucky.

Windproof, cold-proof, warm, waterproof and anti-slip.

Down jackets should be waterproof, and shoes should be waterproof and non-slip. Please prepare a set of "/zd/ym" for the thickest thermal underwear in Uniqlo.
