Long cycling coat recommendations

I’m looking for a long cycling coat for my ride to work, it’s not very far so doesn’t have to be very fancy but ideally long enough to keep my shorts dry as I wear them all day, so sort of knee length if poss, breathable would be good too as doubling up for walking in would be ideal but not totally essential, there seem to be quite a few out there starting at not too much cash, any recommendations for ones people have used would be very welcome.

aren’t long coats and cycling more or less mutually exclusive?

A posh poncho?…

IMBRIS Rain Poncho

Theres quite a selection at Rev Race and some big Black Friday discounts. https://www.revolutionrace.co.uk/men/jackets/shell-jackets

I’ve got a Silence.  I think I tried the cyclone Long as well – it is pretty long for a shell, and big and boxy (less breathable than some I think because theres a lot of double layer stuff with the pockets)

they might look ridiculous but I really like my Rainlegs
