Thank you for the review. For Run & Gun lightweight shooting style that can pack many extra lenses and accessories with reinforce structures and extra front and back paddings this rectangular shape Top Shelf 22L backpack bag in sling configurations is a good design at a premium price tag. I still think my 10+ years old compact tear shaped Think Tank TurnStyle 10L & 20L sling (can be converted into waist pouch style) at 250% less cost ($250 vs $100 and $50 10 ya ago) provides the same stable sling function in a vertical storage format at 366% lighter weight (4.4lb vs 1.2lb) including the build in pull over rain cover. For fast Run & Gun shooting I prefer the lightest possible weight for all day comfort and carrying extra 3.2lb all day long would not be my preferred choice.
