Last year I ordered a bib shorts and a jersey in China, not customized, but an Assos replica. My size in normally M, but the Chinese sizes are a lot smaller. So, I ordered a XL bib shorts and a XL jersey. The bib shorts size was perfect. The jersey size was a little bit to big. Next time I will order a XL size bib shorts and a L size jersey.
Be aware of a delivery time of four weeks.
The chamois/pad is okay. Nothing specials and not bad.
One little negative point is the black color of the bib shorts. The cloth is not black, but white and painted black. When you stretch the cloth, you can see the white a little bit. So, it's not really black. But who care, the price is great!
