Winter CarSeat cover

Ja

What winter carseat covers do you mamas use? (I have the Chhico Keyfit 30) I am in NJ, so it gets pretty cold but not Canada or Alaska cold.. lol

To add, my lil girl is like a furnace, and after like 45 minutes in this.. she gets uncomfortable and you can tell shes sweaty when removing it. So idk if i can keep her in stuff like this right now.. She is 16w...
