Constructed of satin-like Taslan fabric for authentic Thai-style look and feel. These shorts also include an internal drawstring on the waistband for better fit and comfort. Split out-seams allow additional room and comfort for kicking. Sublimated logos look sharp, with excellent durability. These shorts compare favorably with the very best out there! They are cut true to size. If you are going to wear a cup/supporter under them, or if you are between sizes, you might consider the next size larger.
