First let us talk about the yarn. It is the Red Heart Heat Wave yarn. This yarn get warmer when exposed to the sun. The one time I wore this hat, I really could not tell if it did. I am not saying that it doesn't work. I just could not tell. I did feel warm enough around the head and neck, which is what I wanted. One skein of this yarn did make this project.
I had used this pattern I found on Pinterest to make the beanie part:

I had used a size I crochet hook, I started out with the 10 dc in a ring for the first row, did the increases until I got 60 stitches. At this point the crown measured 6 1/2 inches. Then I worked even until done 14 rows total.
To start the cowl part, I did 35 dc and left the remaining 25 dc unworked. Chain one and turn. Dc 35 stitches, chain 1 and turn. Dc in the 35 stitches, chain 25, and join with the first dc. Dc in each stitch to go back to 60 dc. I did eight more rows of the 60 dc. I also did single crochet around the face hole opening.
