Sizes 40 to 46. This is a very good style for men, but women love it too. Just change the button hole band to opposite side for women! It is light , warm and comfortable. It works up easily, simple shaping and easy optional pockets. Uses sport weight yarns, and knitting needles, US # 4, and # 6. There isnt that much work to this as it is mainly stockinette stitch, with ribbed borders. Simple decreasing for shaping. Make one for Dad and Grandpa too!
