The Berserker is a double stranded beanie. It is a great all year hat that is able to breathe due to the open style stitches that are used (even though it looks solid). It also uses Outlast fiber which works with your body temperature so you don’t get too cold or too hot. This beanie is great for sports or works well if you just want to rock a cool accessory. Adult size. This pattern uses the adult 5/8” 48 peg round loom from CinDWood Crafts or comparable loom. 2 colors: Black Outlast (Ice Yarns) and Lily Sugar ‘n Cream (I use the “hot” colors). You will need about 120yds of each.
