Luxury Heavy T-Shirt - 4 PackLuxury Heavy T Shirt 4 Pack 7. 3 oz. heavyweight microrib jersey, 100% GOTS certified organic cotton. 4 heavyweight tees in one order. The 2x2 ribbed collar holds its shape without flaring. Forward shoulder seams and a drop shoulder cut create a modern silhouette that works for both layering and wearing alone. At 7. 3 oz the fabric has enough drape to hang cleanly and resists the thinning that lighter shirts show after many washes. GOTS certification
