I'm going to the beach for a week in a bit. I'm a little concerned about my vape gear. First, the heat. I want to make sure my stuff doesn't get too hot(batteries and tanks). I was thinking about getting an insulated lunch bag to keep it in. Do you think that would work? I'm also concerned about sand getting everywhere and water. Maybe I should keep everything in zip lock bags when I'm not currently using it. Are there any precautions you think I should take? Thanks.
