As above really, these are great and all, the second one is easily the best for you BUT ideally to keep warm and dry you need a layering system....something waterproof and windproof and breathable to keep the inner layer dry. The inner layer just traps your bodyheat and keeps it there. So ideally something like a fleece inside a gortex outer, pref all in one garment that can be split into the two parts with a zip. Obv if you were out in the woods/mountains etc you'd take this a good bit further but just as a casual winter coat then i'd go for a goretex ( or equivalent ) with a zip-in fleece

Fit is importnat, if it's too loose it wont work. Pay attention to how collars and cuffs fit too
