I dont really get that cold, i mean if its below freezing then i cant work anyway so if im out it must be 1 degree or above
so a pair of long johns under work trousers, 2 pairs of socks instead of one.
Work shirt, jumper, hoody maybe a fleece or water proof over the top
hat and gloves if needed
no need to over complicate it just wear more layers i dont know why you need a special coat
I wouldnt be buying them £150 boots
you chaps have too much money
i just wear cheap hiking boots with a few pairs of socks.
