When working with professional camera equipment in extreme cold weather, all items would be double bagged in ziplocks before bringing back inside to room temperature. The danger to the electronics within the camera is the condensation when warming up after being brought inside. With double bagging, the condensation would be take place on the outermost baggie. The gear would need to thoroughly adjust to room temperature over several hours before removing from the baggies. For long term storage, @lpretiring’s suggestion of vacuum sealed sounds good - as long as each bag is sealed individually - and is double-bagged.

@gdnrbob I’ve heard about using rice. But, for run & gun location shooting (photography), there’s too much danger of the grains getting pulverized. The tiny particles could easily find their way into the delicate camera or lens mechanisms. If the gear was in a professional camera case between shoots, I would use desiccant silica gels.
When shooting in extreme cold, I used the baggie procedure before going back indoors. Besides the electronics, it’s important to keep any condensation from forming between the elements in a lens. Every once in awhile, it was necessary to get inside really quickly during a white-out snowstorm - without any time to baggie the gear. When inside, it was easy to see the condensation forming inside the barrel of the lens. The solution was to ’cook’ the lens in an oven at 100 degrees. Then, back to work.
Then, there’s another challenge of putting your hot eye up to the cold viewfinder when back outside. That would immediately cause condensation on the viewfinder glass. Impossible to see anything at all. There’s a couple of tricks to solving that. But, I don’t wish to hijack this thread much more.
