Can anyone recommend a backpack (not a sling) that could fit two Mavics? A bit of background, I am often in scenarios where I am in the middle of nowhere and so a backup Mavic is a must. Still need to pack very lightly though. I needed to pack two Mavics, two controllers, two chargers, 4 batteries, and and two iphone SE's, in one light weight backpack. Anyone here ever pack anything like this? My bud is carrying the portable power cell to charge the batts. I am in charge of this bag though. There are just so many bags it gives me a headache. Any of you young whipper snappers help an me out. Pics would do good too. Let me know thanks.
