Product Name: SAYSKY Running Shorts Men's Size: XS [Waist] 64cm [Hips] 100cm [Rise] 33cm [Inseam] 11cm [Leg Opening] 28cm [Thigh Width] 32cm * Quoted from the official website. Please note. Color: Black (with some gray, patterned as shown in the photo) Retail Price: ¥13,200 These are new SAYSKY running shorts. I bought them about 3 years ago, but at 176cm and 68kg, they were too tight, and I never wore them. SAYSKY uses international sizing, so it's difficult to understand the fit, but they are generally made quite large. For slender Japanese men, XS or S would likely be the best fit. Please check the size information listed here (I recommend searching the official website) and the photos to make your decision. I am also selling a long sleeve shirt with the same pattern separately, so please take a look if you are interested.
