4545 Tenjiku 908 V-neck Short Sleeve T-shirt

This simple T-shirt, designed with a deep appreciation for material, features a gently cut V-neck finished with flat seams. The fit is unisex, making it a versatile piece for all wardrobes.

Our philosophy is straightforward: we want to create clothing that simply feels good to wear. That sense of comfort is at the heart of everything we do.

Using Australian cotton grown in rich, fertile soil, we’ve spun it into a traditional single yarn and knit it loosely for a soft, airy texture. The result is our 4545 (yoi-yoi) jersey—a fabric with the gauzy touch of muslin and a beautifully uneven, heathered surface. Its natural tone reflects the raw charm of the material itself. A quiet example of 45R’s Japanese craftsmanship, where simplicity and care come together in every thread.
