I bought this bunting last winter for my 4 months old for Chicago Winter and am looking to buy one for this winter in Ohio. It is a pretty decent product.
Pros:
1)Truly water resistant fabric
2) Pretty warm with down/feathers fill

Cons:
1) Feathers do come out slowly
2) Fold over mittens and boots DO NOT have the warm down/feathers fill. So for the purpose of warmth they are completely useless. Just a piece of nylon.
3) It is much thinner than it looks on the picture. So it is not as warm as it looks. The down/feather count is probably very low (not indicated).

Overall, however, I do recommend it. It serves  the purpose.
I have not been able to find a better product so far. I will keep looking though.
