That's how you know the presenter might need a break from presenting - people talk more about his jacket than about the information he provided. Just saying.
The Carrier Company design outdoor work clothes. I imagine he might source some of his items from them. I think his leather jerkin might come from Bradley's the Tannery. Your other avenue of enquiry might be to look at country outfitters.
... maybe the Carrier Co doesn't have Monty's jacket, but they do have a range of nice hats! Just ordered one (didn't know I needed one, and wasn't looking, but hey ho!).
