A solution to the fogging on the outside of the lenses is a product called Kleer Vu. It was recommended to me by a technician at Leupold. This stuff works!! Coat the outer lense surfaces of your scope/bino's, and it will not fog - period! Down here on the coast, we get some wacky weather sometimes, and alot of fog - which plays havoc with the scope lenses (I missed my opportunity at a nice buck because of this). A small bottle of the stuff will last for years. I highly recommend it for hunting in the rain - even if you have scope covers.
