Here it is seemingly gone wrong in the manufacture of this product and some Asian sizes were taken as an indication. Care must be taken when ordering that at least two sizes bigger will be ordered, which is difficult because an XL or XXL is not available here. I had an L ordered an XL came, even this was too small. The elasticated laced very uncomfortable, although there is a band in the waistband.
For processing: the material felt good, the seams were well made. The inner trousers had two open seams with me. Also note that swimming shorts are not long but may be shorter, but actually looks good compared to the other products.
I returned the shorts, unfortunately there is no substitute in L = XXL
