100% cotton. Fine ribbed jersey fabric. Ribbed crewneck with V-insert. Ribbed cuffs and hem. Chest pocket with embroidered brand patch. Regular fit. Armor Lux have really pushed the boat out with this Sweat RDC Heritage sweatshirt. Its as laid-back as it is smart Its as decadent as its subdued Its a shining example of what contemporary sportswear should be, but still has that old-world timeless essence about it. Reckon thats enough poetic spiel for now. In short, its a really well-concocted cotton jersey number with a handy little pocket to boot.
