I think the Beadnell runs pretty true to size, it’s supposed to be pretty forgiving. If you want it more generous for ample layers or are in between sizes I think you could go one up but no more – it is a boxy fit. I can comfortably fit a sweater with this; however, a sweater + the removable fleece vest is doable but tight. It’s pretty warm and is a go-to in fall or spring for temps between 50-70. It holds up well, I got this in 2020 and it hasn’t needed care yet. Barbour sells a re-waxing kit or you can send it in, some Nordstroms have also done pop up shops where you can bring it into the store to get it re-waxed.Barbour,8,$395, British Brands,Coats/Jackets,Jacket,Size 8 All Reviews,Barbour,Jackets
