In reply to Mark Eddy:
> I have an old Montane featherlite jacket, something like this: https://www.needlesports.com/Catalogue/Clothing-Footwear/Technical-Clothing... - which I bought maybe 10+ years ago and it's seen plenty of use and still in decent, useable condition. It was in a sale at about £50 and I remember thinking, ooooh that's that a lot. It's been incredibly good value for money. My partner runs in the fells (Lakes) at least weekly, often more and often in horrendous weather. Her latest jacket, purchased earlier this year, was about £120-£150, can't remember the brand, but I do remember it took a lot of deliberating before deciding on it. It seems to work a treat. My old Montane still works fine too, keeps me warm enough and dry-ish.
> £330 for a running jacket is nuts. No doubt plenty of folk will buy these and like them. But there's perfectly good alternatives for less than half the price.
I think you're quite right, there's plenty of good alternatives, and I've reviewed a fair few of them. However, within all the running jackets that I've ever reviewed/owned - this is the one I'd want with me in the worst weather.
When buying cheaper jackets in/around the price point you've mentioned you usually have to sacrifice one or more of the following: waterproofing, breathability, durability. When it comes to durability in particular, I've used and abused a great many 2 and 2.5 layer jackets over the years (which is likely what you're getting when you spend that amount of money) and what's noticable is how much quicker they wear out. I don't think it'd be unfair to say that they're unlikely to last a 1/3 of the timeframe that a decent 3 layer jacket would, so the economy of buying a 'cheap jacket' isn't all it's cracked up to be - at least not in the long term.
