This is a wonderful fleece-backed, organic fiber sweatshirt knit, with a blend of organic cotton and bamboo rayon. It is medium weight with body in the drape and about 10% widthwise, 20% lengthwise stretch (so you may want to lay your garment across the grain). The right side is a plain, flat knit while the reverse has a fleecy, super soft texture. The color is denim (PANTONE 17-4021 is close). This is a casual gem that is perfect for hoodies, casual jackets, cardigans, sweatpants, kids clothing, bathrobe, etc. Manufacturer recommends machine wash and hang to dry, but please test first, and wash separately when you pre-wash.
