Jackman Comp Wool BB Shirt - Navy
The Comp Wool BB Shirt reinterprets the classic collared baseball shirt with a refined blend of structure, texture, and craftsmanship. Made in Japan from a premium wool-nylon mix (65% wool, 35% nylon), the fabric is created by applying strong heat and pressure to knitted wool ring yarn — a process that gives it a distinctive, firm hand reminiscent of melton wool while preserving a soft, rounded feel.
Ring yarn is crafted by twisting wool around a thin, durable core yarn, stabilising the natural irregularities of wool while enhancing strength and longevity. The result is a material that balances toughness and comfort, with a unique surface texture and dimensional appearance.
The design draws inspiration from early baseball uniforms, featuring a collared neckline for a vintage athletic look, large swing pockets for functionality, and a versatile shape that transitions effortlessly between outerwear and casual layering.
