Lowepro Slingshot SL 250 AW III Mirrorless and DSLR Sling Camera Bag with QuickDoor Access and 10 inch Tablet Compartment DSLR Accessories - for Sony A7, iPad, Surface Pro - 300D Ripstop - Grey

I go on photo expeditions by rail at least twice a month and needed something small and light that could carry a DSLR, 11" iPad and my basic travel kit and this checks all the boxes. Perfect size. The bag itself is more or less weigtless. I'm using a conventional DSLR with a long zoom lens, not a mirrorless version. There is a pocket on the side that a reporter's notebook fits perfectly. The single strap ("sling") design makes it easy to carry. The zippers have loops on them that yoiu could lock with a small, TSA-approved travel lock — not so much for security but to keep the zippers from being opened accidentally. I wish they'd put a business card/luggage tag slot on the back. This will make a great day travel bag too. It's bigger than a messenger bag and less bulky than a duffle bag, but probably too small for overnight trips. Great for limited outdoor hikes too. Since the storage compartment is on top, I would avoid packing liquids as they might leak all over the camera below.

I was able to get my Canon R6 (w/o the battery grip) to fit with my Canon 70-200mm or the 24-105mm attached. And there was plenty of room for the lens that was not in use as well. This all fit in the lower portion. The top pockets held an extra set of batteries. Lanyard. Cell phone and wallet. Keys. And a DJI Action Cam. With room to spare.Perfect bag for a quick trip or for flying. Especially if you only needed one or two lenses.I tried several other brands and no of them could accommodate the height of the R6. This one did with a few centimeters to spare.Highly recommend!
