Your experiences with Rain covers for camera and lens?

In a light rain, I will trust the weatherproofing of my cameras/lenses. However in heavy and extended rain, such as during my trip to the Kenai Peninsula of Alaska when it rained heavily for 10-days

Thanks for your findings and advice, I will try that Optech Rainsleeve

my wife got a fairly nice cover for me off Amazon. not sure of the brand but it has two "sleeves" where i can insert my hands for use and accessing the lens. it has a draw string to tighten down around the barrel of the lens but its just barely big enough for my 70-200 f2.8. had to remove the foot/tripod mount from the lens to get it to fit...

They don't make Kata covers any longer, and the Storm Jacket, which looks nice, doesn't ship on time. Funny, it's listed as Amazon Prime, but it takes a week. Any other good choices I can get quickly and at least dry fit before I jump on a plane? This is one of those times I wished I still had a real camera store close by.

OMG, every decent camera store is closed until 10/3. I want to weep.

*Nevermind; I'm an idiot. Helps to actually be logged into the amazon account. Travel turns me into a panicked, brainless ball of useless mush.
