Alright, basically instead of going cold to cold, or cold to hot, it's being shipped from hot to cold, so how do you work with that?

The lows are in the high 50's at night, but it's hotter from the other side of the states so that would eliminate using a heat pack because it would toast right? So how do you do shipping from hot to cold?

Does such a thing exist as far as a temperature activated heat pack? I don't believe so but it's always worth asking, so if not can anybody give me any advice as far as this is concerned?
