Lands end here too. Only ones that keep me warm. Squall parka for wet weather and a down one for cold cold. Ive brought a next padded coat which says its shower proof this year as wanted something slightly nicer but im not sure it will be too warm at £50 and polyester filled.
Good hat scarf and gloves are essential. Layers are good. I wear at least two vests under my clothing. I never wear jeans or trousers so black thermal leggings instead of tights. Two pairs of socks one normal pair and then a pair of thermal or those fleecy bed type socks and then wellies.
