Woven from extra thick yarns, the No. 7 Yarn-Dyed Indigo T-Shirt is heavier than the already heavyweight No. 8 tee. The yarn has been rope-dyed, a meticulous, somewhat rare, process which leaves the core of the yarn white, making for a fabric with a high fading potential. Because of rope-dyeing's high color transfer potential, very few factories in Japan are willing to produce yarn this way, lest they stain all their machinery! The heavy, slubby fabric will soften up and lead to unique fades with good wear and wash.
