I was a little disappointed at how thin this jacket was.  I was looking for an "in-between" jacket, not light, but not heavy.  Unfortunately, this is a light rain jacket so not what I was looking for.  However, that's because I didn't read the description close enough.

Instead, I wear this coat over my down coat to serve as a windbreaker and to keep dry.  It does a fantastic job and goes over my down coat nicely.  In -40F weather, I am toasty warm in this jacket combined with a light hoodie and a heavy down coat.  It keeps the snow from melting on me or the wind from cutting through the other coats.
