Car seat blankets

[Summertime10]

Hi everyone
Does anybody have recommendations for blankets that go into baby's car seat to keep them warm in the absence of using a coat please? I'm aware there are some that are not recommended but others have been safety tested for use in a car seat.
I've seen the Morckk (sp?), which seems good, but I was wondering whether there were any others worth considering?
Thanks in advance!

I used a normal crib blanket, strapped ds in then tucked the blanket in around him. He always seemed pretty toasty. You can always bring the baby seat into the house to warm up if it's really cold.

I have an excellent picture of him on his first trip out, he is tucked in with a little hat on, and all you can see is a highly suspicious pair of eyes giving the world at large a good side-eye

I never found it necessary to use a blanket, and I would have worried about it covering the baby's face. You shouldn't put them in anything padded, like a snowsuit, but a jumper or non padded pramsuit is fine.
