Bought a marked medium but it's the size of an extra large. Be aware you probably won't get what you expect, fit-wise.

I have multiple Adidas regular fit track jackets (which this is listed as both here and on Adidas sites) and medium is always 22" pit-to-pit (which is pretty standard across brands, with small 20", large 24", and etc.).

This arrived and it has a 26" pit-to-pit measurement, which should be marked as an XL jacket. Tried to start a return as a defective product but would have to pay for shipping so I guess I'm stuck trying to locally sell a jacket I can't wear so I'm not out of pocket.

You might like the look, but don't make the same mistake I did.
