NYLON METAL IN ECONYL® REGENERATED NYLON_GARMENT DYED: Swimming trunks made in a new responsible Stone Island iridescent Nylon Metal fabric. The evolution of this iconic fabric sees the use of ECONYL® regenerated yarns: the life end of nylon, pre- and postconsumer, is recycled with a complex depolymerization process to create this fiber that features the same intrinsic characteristics of nylon from raw fossil materials. The finished piece then undergoes an elaborate double dye procedure. In-seam hand pockets. Small pocket with hidden zipper fastening on the upper right front. Tonal Stone Island Compass patch logo on the bottom left leg. Piping on side seams. Inner mesh. Elasticized waistband with inner drawstring.
