I live way up north in cold conditions. This jacket has no insulation, will it do me any good?
Well, shells will definitely block wind and moisture, so if you layer properly you can be warm in the coldest of conditions. If you are looking for a jacket you can wear if your going for a snowy walk with some friends or hopping around town, I might suggest getting a warmer jacket. If your shredding on a 23 degree day, your going to be putting out some body heat, so with a baselayer, midlayer, and a shell, you should be OK.
If you get cold really easily, look for a jacket with some polyfill insulation, this means low bulk with high warmth!
