I also like biosport and brisping belts but I think those spikes could tear other clothing.
And finally I got Thavar 807V for good price. It's actually my first pair of Diesel, where is a bit mess with inner tags, one tag was cutted away and there are 2 at zip fly. Strange. But I'm sure, it's authentic + bought from dress for less.
Btw. did anyone try to re-iron the waxy shine?
