A ribbed polo shirt finished with a double mercerization process, offering both elegant sheen and exceptional comfort. By applying mercerization twice—from yarn to fabric—we achieve a rich, lustrous finish with a supple yet structured texture.
Additionally, by using tightly twisted yarn, the fabric resists clinging to the skin, offering a pleasantly crisp and cool touch. The appearance is breezy and refined, making it perfect for staying comfortable even in hot and humid weather.
Design Highlights The ribbed collar is enhanced with a stand collar (collar band), giving it both structure and a polished appearance.
The collar holds its shape well, making it suitable as an inner layer under a jacket.
The ribbed sleeve cuffs provide a clean, tailored silhouette.
Subtle melange colors add a refined, understated elegance without being too flashy.
Recommended Styling & Occasions Pair with slacks for a refined business casual look.
Match with chinos or denim for a stylish, relaxed outfit.
Thanks to the structured collar design, it also works great layered under a jacket.
About Mercerization Mercerization is a treatment in which cotton yarn or fabric is stretched and immersed in a sodium hydroxide solution to achieve a silk-like gloss, increased strength, and improved dye absorption. This process enhances the cotton’s durability and softness while producing a beautiful luster.

This jacket embodies everything that epitomises Ivy League styling, the cut the choice of colour and the quality of workmanship are all exceptional, and so too is the fit. I am so pleased that I discovered Kamakura!
The product received is spot on to the description. The material and the color are excellent. On sizing a small is a snug fit for me. If you want a more relaxed fit or plan to wear an undershirt get a medium.
The boring bit: Delivery from Japan was fast and seamless.
About the shirt:
I've been wearing OCBDs for over a decade at this point from various makers. I now regard this as the benchmark because it's a quantum leap above the rest. The cloth is satisfyingly heavy and yet beautifully soft. The roll on the collar is delightful and the cut of the shirt itself is roomy without being baggy allowing you to move without hinderance. The end result of this is a shirt that is comfortable enough for a lazy Saturday and yet smart enough for the office.
