I considered a number of drone backpacks, various brands, various price ranges, but in the end I homed in on the Lowepro offerings, because I have several of their products, and know them to be well designed and well made - perhaps the best of the bunch. Then I had my internal price vs product debate, comparing and contrasting the 200 & 250 models; the former being considerably lower in price. In the end, I went for the 250, knowing that it would take all of my existing gear and still have spare capacity, for new batteries, etc. As my headline suggests, I'm using this for my Mavic Air rather than the larger Mavic Pro. I am able to store my Mavic Air in its own 'clamshell' case, making sure that it is doubly protected. The compartmentalised backpack is able to store all of the contents of the 'Fly More' package with space left over. There is a large pocket next to the back pads, which I am using to store the A4 folder containing my printout of the full DJI Mavic Air manual, but this could equally take a laptop of similar size. This pocket has a second internal pocket which is sized to take a standard tablet. There is also a large compartment at the top of the pack, which could take a variety of other items, including other camera equipment, or a storable spray jacket, or suchlike. The backpack is very well designed and is of a quality that I have learnt to expect of Lowepro. As I have said, it is capacious, but its external dimensions are relatively compact and sits well on the back, comfortably. Particular to my needs, the whole backpack fits inside the rear top-box of my motorcycle (note: it is quite a large top-box). The Mavic Air 'Fly More' package comes with a very good shoulder bag. I will still use this when the situation makes it more suitable, but the Lowepro backpack will be my primary carry-everything 'base station'. It is worthy of note that the Mavic Air 'Fly More' shoulder bag fits snugly into the top compartment of the backpack.
