How to use these specifications
Start with the size of the objects you carry. Compare them with usable internal measurements when available, then check pocket access and closure with the actual load. Published outside dimensions are a screening tool; they do not establish internal clearances.
A shoulder-strap length, strap drop and complete wearing circumference describe different measurements. Keep the stated measurement type when comparing bags. Manufacturer descriptions of protective features are claims, without a CarryFacts security test.
