This overshirt is crafted in Supima cotton twill stretch, made with mercerized Supima cotton yarn and elasticized. Supima - Superior Pima - is the guarantee certificate for the US origin of Pima cottons. This is the noblest species among cottons, due to the greater length, uniformity and strength of the fibers. The overshirt is garment dyed and features two patch pockets and a two-ways zip fastening. A signature Stone Island badge decorates the left sleeve.
