THE BUSINESS-T, A refined T-shirt for the modern professional, perfect under a jacket
A new essential T-shirt designed for today’s businessman, offering a clean, polished look whether worn on its own or as an inner layer under a jacket. Made from our signature PREMIUM CIRCULAR fabric, also used in our stretch shirts, this business-ready T-shirt combines quality and functionality, setting it apart from ordinary casual tees.
Cotton 47%, Polyester/Polyethylene 53%
Made in Japan
Material
The outer surface features 80-count SUPIMA cotton, known for its smooth texture and elegant sheen, while the inner side uses a composite fiber (polyester + polyethylene) for comfort and performance.
Special fibers prevent light from passing through, achieving a “white yet non-see-through” effect.
Polyurethane yarn is knitted into the collar, providing stretch and allowing it to flex comfortably with neck movement.
Functionality
Maintains a smooth, dry feel even when sweating—ideal for business settings.
Excellent recovery (kickback), helping the fabric retain its shape and resist deformation.
Offers UV protection to shield your skin from strong summer sunlight.
Opaque enough to be worn on its own with confidence.
Design
The neckline features a slightly wider rib. This adds subtle volume and structure around the neck, giving a simple T-shirt a refined accent.
The collar is designed slightly higher to prevent direct contact between your skin and the jacket, helping reduce wear on the jacket.
Ideal for business casual outfits.

I own about a dozen Kamakura OCBD, and at least 5 in the Vintage Ivy series. An extra button at the bottom of the front placket would be great for taller people, but that's just a nice to have. The shirts get better with washing, except the NAVY one. The color fades (to be expected) even with cold washing and air drying. I find it makes the shirt a little less attractive than the others. It's a common problem with dark navy cotton garments after repeated washing. I will buy more Vintage Ivy shirts for sure, just not this color.
This sweater does everything I wanted it to do and more. Casual or dressy. Cozy but never hot. An heirloom quality piece to last my lifetime and for one of my kids to inherit and enjoy. Thank you Kamakura Shirt for your good taste, and intentionality in quality execution.
