Check your airline for the kgs. Some more generous than others. Some also more flexible on size of cabin baggage too which heavy stuff could go into if bags maxed out. Just bring a few things you can layer up on cause as said it's the wind chill which I didn't understand until I got there but it hurts it's so cold so few leggings and long tops with cardis kind of layering is good. All stuff that can easily roll up in case very small so you are only taking the bare essentials. I tend to wear a crapoy pair of shows that I chuck away so one less pair to bring back and room for a new pair
