With the Box Shirt, Sugar & Co. presents the second generation of its popular Board Shirt series. Inspired by the legendary board shirts of the 1960s, which became world-famous through California's surf culture and icons like the Beach Boys, this shirt combines authentic vintage aesthetics with exceptional Japanese fabric development.

Typical for a classic board shirt are the straight-cut hemline, the shortened length, and the generous chest width. This characteristic box silhouette ensures a relaxed fit and gives the shirt its casual, distinctive look. Whether worn open over a T-shirt or as a standalone statement piece – the Box Shirt embodies the relaxed elegance of the American West Coast.

For this model, Sugar & Co. uses an exclusive fabric from Niigata, a region of Japan known for its exceptional textile artistry. The fabric is made of 100% cotton but has a surprisingly wool-like appearance and feel. This is due to the elaborate "Mikoyori" technique, in which three individual yarns are twisted into a single thread. This rare process creates more volume, increased durability, and an exceptionally soft, vibrant texture.

The result is a fabric with a pleasant substance, excellent moisture absorption, and natural temperature regulation. This makes the shirt suitable not only for spring and summer but also works wonderfully as an overshirt or layering piece in the cooler months. With increasing wear, the surface of the fabric changes and develops an even more expressive, almost wool-like patina.

As with all Sugar & Co. products, material quality, comfort, and timeless design are paramount. The Box Shirt 2026SS is a versatile heritage shirt for lovers of Japanese craftsmanship and authentic Americana fashion.
