Scandinavians know how to dress for forbidding weather. The long Scandinavian winter, which typically stretches from November until late March, demands layers of clothing and plenty of protection against the cold. While temperatures can plummet to -30C (-22F) farther north in Sweden and Norway, winters farther south in Sweden, Norway and Denmark tend to be milder and wetter, requiring breathable materials that also withstand rain.
Moving abroad to the UK and then returning to Sweden, I realized how underdressed people were outside Scandinavia. It became even more obvious after having kids and noticing how we always try to dress them appropriately, including several layers of clothing that are finished off with a pair of thick shell pants.
