Rain gear ??

[McMurdo]

I would say an Inverness is your best bet, I've heard nothing but good about the Mr. Anthony Inverness Cape, I know many vendors carry them, the other option would be the Empire Canvas Works Storm Cape that you can get through the Scotish Tartan Museum

EDIT:
Here is my Inverness Cape, made by our own vmac3205




It has not seen a real downpour as yet, but has held up wonderfully in the rain we've had since it's arrival, perhaps you could get in touch with her about one for yourself.
