Rain covers

Morning All, Been hunting around for a new rain cape, fair bit of stuff out there with various ratings. Kata and OpTech seem ok but wondered what the feeling was at the 'coal face' so to speak. Having spent a few hard earned quids on my kit I want something that realy works.
Anyone with 10/10 for something?

Hotel shower cap!

Cheap - effective - disposable.

Works for me!

B. (typical tight Jock :wink

Used those plus condoms with my old 35mm Minolta, worked ok but go a lot of funny looks.
Just had a thought!! A vets long glove, the ones they use for internal examination of cows etc. Might fit a 645. Will give it a try and report.
Thanks for the trigger B.
