what about these? i got them for my older sons. i ordered them extra big so they would last for a couple years. generally with winter coats i tell them to not wear them in the car & they use a sherpa lined sweatshirt jacket for the car but i think these maybe thin enough. i mean they are in just seatbelts not in a carseat anyway WDYT? they said already that they are quite warm jackets even tho they don't look it
