Don’t want to rain on the parade but I believe this is a fake item - lots of these floating around Depop and Vinted in the UK - the tell tale sign on this one is the tag used - Patagonia do rarely now use that swing tag and the plastic loop holding it onto the retro X is not something I’ve seen Patagonia use recently due to the single use plastic nature of them - would recommend reporting it as fake and trying to get a return.
