Gert a couple of weeks ago in KMart where umbrellas are, we bought some raincoats that fold up into themselves and they're really compact, for $10 or $15. They're great and easier than carrying a brolly in your situation .... I got one for DH and I mainly for camping .... but we leave them in the car and they're very handy. They're navy blue, I think they're mens but who cares, if they keep you dry !
