Zipp has sleeves that are removable so it can be worn either as a vest or a warm, outerwear pullover. The zippered sleeve “seams” are left exposed as a design feature. Match the color of the zippers to the yarn or choose a contrasting color so they really stand out. A half brioche ribbing stitch edged with a contrasting color is used on the lower body, cuffs, and neck.

To really mix things up, why not knit an additional set of sleeves incorporating some stripes or different stitch patterns? He can mix and match the sleeves according to his mood or outfit.
