Parka recommendations

Hi guys! I need to buy a warmer coat and looking for some Parka recommendations for Central/Eastern Europe winters (0 to -10 degrees Celsius). My budget is 400-500 euros and the most important feature would be to keep me hot. It'd be great if I can try it in the store.

So far I like this one from Fjallraven Nuuk Parka M , anyone knows how warm is it?

Also, what are the opinions on the brand Wellensteyn?
