In reply to GraMc:
I've just had first class service from Patagonia for repair of a Nano Air and an R1 hoodie. It wasn't especially quick (but totally understandable given the times), but the repair company that they use in the UK did a very good job indeed of both. Amazing in fact. I wasn't expecting much from the nano air (my own fault - I managed to set it alight - don't ask!!) and thought it was for the bin. The repair is visible, but the jacket is functionally as good as it was when new.
Couldn't recommend both Patagonia and Lancashire Sports Repairs in Burnley enough. Patagonia even emailed a pre paid label through to me for the carriage costs down to Burnley.
