The Nylon Ballboy Shirt is crafted in Japan from 100% nylon, woven in an Oxford weave, then garment-dyed and treated for a pronounced crinkled finish to recreate the patinated look of 1960s nylon garments. Its construction is inspired by the coach shirt and features a large chest pocket combining a compartment modeled after ball boys' ball pockets and an easily accessible hand-warmer opening. The elasticated cuffs are finished with small slits that make it easy to put on and allow the sleeves to be pushed up quickly.

With its textured nylon, functional volume, and oversized pockets, the Nylon Ballboy Shirt sits between a lightweight shirt and a utility jacket. It is easy to wear over a T-shirt with denim or loose-fitting trousers and reflects Jackman's singular approach, which revisits clothing inspired by American baseball through precise, contemporary Japanese manufacturing.

Originating from Fukui, Japan, Jackman carries on the legacy of Mitsugu Tanabe, founder of Tanabe Meriyasu, whose fascination with American baseball led him to create a post-war workshop specializing in sports equipment. Today, the brand preserves this DNA by combining historical sports references, Japanese textile expertise, and original interpretations of functional clothing.
