I have a really warm waterproof Didrikson coat, going into its fourth winter. The DC have what look similar, but theirs are from M&S and Next, and they get wet and cold on the walk to school and while we are out and about at the weekends. Is there an equivalent warm, dry coat for kids please? I have a tiny one and primary school age. Not bothered about looks, just need it to work (although ideally in a bright colour or with light reflectors to keep them safer on dark afternoons). I feel bad being toasty while they shiver!
