We are moving upto Scotland in 3 weeks time and I don't have a warm waterproof coat. I would like an insulated and warm coat for the school run and for long walks. Budget maybe about £200 at most, bonus points if I can get it from John Lewis because I have a voucher to use. I'm 5 foot 2 so nothing too long I guess but I'd quite like something a bit longer than usual I think? I've heard RAB are warm but most are not waterproof? And I've seen some Columbia that look good on JL website but I don't know anyone who has one so don't know if there any good. Thank you!
