BLUE BOOKS CO.
BLUE BOOKS CO. is a semi-custom hat brand that started in 2011 with a belief in “our own production background.” The brand features unique designs not found in other brands.



Note: Production periods may result in crowns being positioned to the right or left. Please note that it is not possible to select the version you would like.





Different Atmospheres by Color
The 10-ounce denim features white stitching that highlights the design. It has a good balance of firmness and softness, and its texture improves with wear, offering enjoyable aging.

The TC twill, made from a polyester and cotton blend, uses stitching in matching colors. This densely woven fabric has a smooth feel and a subtle sheen, giving it an elegant appearance. Its durability is also a notable feature.





Handcrafted Quality in Every Detail
At first glance, it may look like a standard baseball cap, but upon closer inspection, you’ll see that the crown is intentionally misaligned, adding a unique and intricate design. The stitching on the brim also reflects this intentional misalignment.





The fit can be adjusted with a cowhide adjuster belt. The meticulous details, such as fine stitching, reinforcing eyelets, and buttonhole reinforcement, showcase the skilled craftsmanship involved.





Unique Yet Versatile
Although the design is distinctive, the hat features a well-proportioned depth that makes it easy to wear. The unique pattern adds volume to the back of the head, making it suitable for various head shapes and more comfortable than it appears.

The hat is made with a crease-friendly stiffener and hand-finished interiors, adding to its handmade appeal.
