Men's Castelli Squadra Stretch Cycling Vest

Castelli style no. 4521512 Medium sizes can definitely vary. This is a smaller sized, fitted medium. The gray panels on the sides are a stretch material, but you are somewhat limited on size by the elastic around the bottom. There is a slight imperfection on the last closeup picture, but nothing that will affect performance. I think this color orange is the best for visibility too. Good, used condition.
