depends on how windproof and coldproof it is. I guess the only way to find out is thru trial and error. Good luck.

I bought a shell jacket from Target not too long ago and it's been doing pretty good so far in the early commute when it's 23*-35*f. So far so good but I'll find out once we hit the single digit temp here in the twin cities.

Not exactly, any jacket has an insulation layer under. The air trapped under the jacket act as an insulation layer. The air which is used in most if not all of the insulation on the market is one of the best insulation available today. That's the reason why 2 small insulation layers are better than a single big one. But there are some conditions in order for the air insulation to work best. The jacket must be close fitting enough to avoid a gap bigger than 1cm to limit convection movements and the jacket must be loose enough to limit thermal bridge creation, there is also the ability of the jacket to limit wind permeability. On a bicycle those ideal conditions are usually never there, because of the wind in general and on a road bicycle in particular where due to the riding position the jacket tend to touch the back and shoulders creating a thermal bridge and loosen up on the front creating convective movements
