Life / Winter clothing what to buy in Poland [5]

Hi Guys,

I have just moved the Poland and my Indian jackets doesn't seem to work in this weather, I want to buy proper clothes for Winter, would love you suggestion.

I know now that I will have to buy clothes for layering. I am thinking to buy some thin down jacket to wear inside and then some ski jacket to wear outside but there are so many brands and so many options not sure what to look for. can you suggest me some good brands for following things, I hope I can buy eveything around 600.

1. good down jacket which I can wear inside
2. Good outer jacket, which resist rain as well
3. Good boots which resist rain
4. some warn under garments

Please suggest me some brands and if you like you can send me link from allegro. :)

Thanks
