Sigr Product Sizing
All of our products are designed and made to fit the following body measurements which are an average of European body data. If you are a Medium when you buy a jersey then it's quite likely you'll also be a medium in other garments such as jackets and bib shorts.
This is not always the case of course as we are all slightly different in shape, so measuring yourself might be a good idea just to be sure.
There size charts on every product page too.
