Well, I’m revisiting this thread as I’m of on a trip/flight to Boston area soon. Tried the Peak Design 10l sling, but sent it back. Barely fits my 2018 iPad Pro 12.9” w/Apple folio. My concern was the tension the laptop/iPad pocket put on the top and bottom of the in place iPad.
Otherwise, the 10l would have been a winner. Well maybe except the thinly padded sling strap.
I dug out an old Incase sling, and it fit the iPad better and had a sling strap that was padded better. But, I doubt the Incase was as weather resistant as the Peak Design. The Peak design overall storage was incredibly adjustable!
I do have a ThinkTank Urban Design backpack, but I don’t want to struggle with two straps on the flight or around town. I’m only toting FUJIFILM XPRo2 with 23mm, 35mm and 50mm f2 lenses. I wish I could find a decent bag. Im also carrying the aforementioned iPad and Bowers and Wilkins PX headphones.
My only, owned, alternative is a ONA Brixton messenger bag in canvas. Downside is the overall weight, from the strap, and I’m not sure about rain resistance.
Any suggestions would be appreciated.
