The Pure Blue Japan Slub Yarn Sweatshirt is a seamless fusion of comfort and style that showcases the brand's mastery in fabric craftsmanship. This loopback sweater in Greencast Indigo effortlessly captures the timeless charm of indigo, making it a versatile and universally flattering addition to your wardrobe.

Woven from 100% Long-Staple Cotton, this masterpiece ensures a unique level of comfort. This Greencast Indigo version features yarns that skillfully marry classic indigo with green sulfur dye, resulting in a jersey fabric boasting a distinctive green-indigo hue that ages with a unique patina over time.

This slubby crewneck is a nod to the roots of the denim industry. Its slightly slim, tailored fit and raglan sleeves offer a modern silhouette that seamlessly integrates into various styles. The seams, marked by a subtle contrast, evoke a lightly worn look, reminiscent of vintage aesthetics. Refined details, including ribbing at the collar, cuffs, and waist, underscore Pure Blue Japan's commitment to quality. 

Pure Blue Japan's tops run small, being one size smaller than your regular American size. As always, we recommend consulting our size chart for the perfect fit.

Pure Blue Japan is the dream of Kenichi Iwaya. Passionate about denim, he grew up in Okayama and acquired experience working in different mills around the region, until in 1997 he decided to create his own brand. Ever since, Iwaya-San has been obsessed with producing incredible fabrics with unique, slubby textures and a distinct character. This is why he only works with shuttle looms from Ibara, Okayama, using only the best cottons from the United States and India. Since its emergence until today, Pure Blue Japan has consolidated its position as one of the touchstone labels in Japanese Denim, and its excellent work has established it as one of the masters of indigo dye.
