I keep mine in a lowepro photography bag with my DSLR, couple lenses, and filters. I can fit the entire fly more combo in the bag (obviously not the DJI bag, but all the accessories). My tripod straps in on the bottom of the backpack so It's basically a full on photography setup that I can easily hike with or take on a motorcycle.
So on top is the dslr with 18-55mm lens, slightly left of dslr is some filters for it, bottom middle is a 55-300mm lens, right side is mavic with battery on, and one spare battery, left side is controller, other spare battery, and ND filters for Mavic. There's a pocket on the front that holds the extended legs, charger, multi-charger adapter, powerbank adapter, spare props, a little air cannon for blowing dust off of lenses, and microfiber clothes for cleaning off any smudges (sometimes it's hard to install those tiny little ND filters without accidentally touching the glass).
