This is strictly a rain jacket, nothing more.  There is no lining whatsoever, so it won't provide any sort of warmth.  It will do well for a summer rain jacket but my daughter definitely won't be able to use it when its cool.  I'm content in my purchase, but I wish they made the sizes easier to understand without having to research it.  I purchased a large for my average sized 9 year old and it fits with a little room to grow into.  I wouldn't purchase this again, but its okay.  Its also a bit overpriced for not having a liner.
