I ordered 2 pants: 1 black / gray and one black / Cyan: The Grey correctly size "M" Cyan size at least 2 sizes smaller spite labeling "M" apparently different manufacturer. After 1st exchange request for service: We wonder 20 exchange fee + return at my expense too quick jog !!!!! Also impossible to know what size this model could match my request to "M". I suppose M = XL for this model. After threat of unflattering comments against them: The seller told me to keep too small (no interest, but at least I do not pay back) IT offers to send me the same model but larger only it is for me to guess whether L, XL, XXL or will do. Waiting for pants XL (to my peril) one week still nothing (control problem). After new contact ... Wait one week again and then mail them to mean a refund because the package is lost ??? !! Not serious seller two weeks to try to resolve the issue. Hard Hard. I always need the pants, but I did not order it here Too much uncertainty about the size.
