4545 Tenjiku 908 Polo

With a twill cotton collar and placket for contrast, this polo-collar T-shirt is thoughtfully designed for easy layering. A casual yet considered piece that blends texture and function with quiet confidence.

Our philosophy is simple: to create clothing that brings joy in its comfort. That feeling is at the heart of everything we make.

The fabric is crafted from Australian cotton, grown in rich soil and spun into traditional single yarns, then softly knit into our signature 4545 (yoi-yoi) jersey. The result is a gauzy, gentle texture with a subtly mottled, heathered finish—bringing out the raw charm of the cotton itself. A natural expression of 45R’s Japanese craftsmanship, where every thread reflects thoughtfulness and care.
