Pure Blue Japan 5409-ID Yarn Dyed Indigo Sweatshirt
The Pure Blue Japan 5409-ID Yarn Dyed Indigo Sweatshirt offers more than just classic comfort — it blends artisanal craftsmanship with a unique fading potential rare in modern knitwear. The fabric is 100% cotton, dyed at the yarn stage in Pure Blue Japan's signature indigo (the same yarn used in their celebrated SS-5011-D dark indigo T-shirt) before being knit into the finished cloth.
This yarn-dyed construction produces a textured, streaky surface with a subtle melange effect that flat-dyed knits cannot replicate. Over time, the indigo fades beautifully, developing a personalized patina that reflects the wearer's habits and the natural rhythm of daily life.
The fabric is knit slowly on circular machines without tension, producing an exceptionally soft, full hand feel and a relaxed, comfortable wear that improves with age. The interior has a subtle terry-like texture that adds warmth and softness against the skin.
Construction features raglan sleeves with gusseted underarms for extra mobility, paired with drop-needle ribbing at the collar, cuffs, side seams, and hem — yarn-dyed in the same indigo as the body, ensuring the rib panels themselves also develop fade and character alongside the rest of the garment. A Shoai leaf embroidery at the side seam serves as the brand's quiet signature.
Fit Notes: This sweatshirt runs small. Compared to most global American brands, we recommend sizing up one from your usual size for a comfortable fit. As a reference, a size 4 (L) fits similarly to a standard American Medium. As always, we strongly recommend checking our size chart and comparing it with your best-fitting sweatshirt to ensure the right fit.
