Nikon D60 body/lens weather armor?

I'm looking for something that will protect my Nikon D60 from inclement weather such as rainfall or snowfall (especially snowfall). Does anyone know where I can get something that I'm thinking of? I was given these disposable plastic covers that can go over the camera and tripod but it's just too flimsy and made great

Added (1). I have the op/tech USA rain sleeve and I definitely do not like it.

An optech raincover works well and is not flimsy.
