Our polo shirts are designed with extra attention to detail. Instead of the usual overedge stitches at the back of the placket, we have added topstitching to give a more refined finish. We have also meticulously processed the back side of the shirt, which is usually hidden, to achieve a polished appearance. Furthermore, the flat topstitch provides a comfortable feel against the skin, making it perfect for wearing on bare skin.



Side seams

The shirt's sides feature flat felled seams that are topstitched for a comfortable feel against bare skin. Typically, only overedge stitches are used in this area, similar to the placket.


Chest pockets

The pockets on both chests provide a good design accent and can be conveniently used for small items.



The cuffs are made of self-fabric and ribbing, enabling the sleeves to drape gracefully over the sleeve cap.


Body hem

Side hem slits with extended back. The design prevents the back from showing even when bending over.


Thread shank buttons

Each button is carefully root-rolled one by one. The thread shank not only increases the strength of the button but also creates a gap between the button and the fabric, which has the advantage of making the button easier to put on and take off. The buttons used are also made from rare natural shell buttons.


Extra-long staple fiber Supima cotton

The fabric is made from Supima cotton. This extra-long staple cotton (ELS) is produced only in certain hot and dry regions of the USA and is highly rare, with less than 1% of all cotton grown in the world. High-quality extra-long-staple cotton, which has the longest fibers of any cotton, is approximately 38 mm long, has excellent uniformity and the fibers have a natural twist to them.



The "88/2 Interlock" fabric is created by twisting two 88-count fine yarns and knitting them in a double-knit construction, resulting in identical smoothness on both sides. circlelabo's interlock fabric undergoes a unique mercerization process that applies alkali treatment and tension to the yarns twice - once at the yarn stage and once when they are turned into a fabric. This gives the fabric a smooth feel and a silky sheen, enabling more vivid colors to be expressed.
