I've found Lavenir better. They rip on wire possibly easier than a Barbour, but the 'moving parts' don't crease & subsequently leak. You can go backwards through thick thorns & brambles better than any other coat I've tried: And I've tried many. Some can't even take a good push through a gorse bush.Good idea, there must be plenty of lightweight modern breathable coats on the market these days.
So please let us all know which one will be as waterproof, tuff or long lived as a proper wax jacket.
I don't have the Rayburn going in the summer...The DIY route is a summertime job at this time of year just too much hassle so £30 pounds is cheaper than a new coat.
