Diesel jeans feature a label on the inside which features an Indian Head and says -DIESEL-ONLY-THE-BRAVE DIESEL-. Underneath the head it will say 'SIZE', and to the right will be the size number.
Underneath the Indian Head tag there should be a wash label including country of manufacture. These countries can include Italy, Tunisia, Morocco and Romania.
The wash label features a lot of product information in a number of languages. It is important to check that the Model (MOD) matches the model of the actual jeans.
On very close inspection there is a thin line of micro-stitching on the Indian Head tag that reads 'Diesel'.
New Diesel jeans are accompanied by swing tags. Check that the registered trademark R is present and for any errors in the Diesel logo size, shape and font.
Most Diesel jeans feature a logo in the front right hand pocket. It says 'Diesel Industry' followed by the red Diesel 'D'. And underneath says 'DENIM DIVISION' in red.
Some buttons and studs on Diesel jeans are branded. Check that any engraving, stamp or emboss is cleanly finished.
