I bought this coat last winter. Its very, very warm. Yet it isn't bulky at all. I find that if I wear a long sleaved shirt underneath that I won't be cold at all even in the most frigid temperatures. I had it on on Sunday when I shoveled the driveway in that blizzard and I was sweating like a pig afterwards. I love it.

I got the black coat. In the link it states that only red is available. UA makes good stuff so another style will probably be similiar in a different color.
