I used worsted acrylic yarn to crochet both of my hats. I was supposed to use 5 mm hook (size H), but instead I used 3.50 mm (size E), which resulted in a very firm and dense feel of the hat. It is great for a windy and cold weather. However, if you prefer something softer, you can adjust the size of the hook accordingly (use bigger size). Of course, then the number of rows and number of increasing stitches would have to be adjusted as well.
