Laptop and bottle dimensions
Measure the laptop with its cover and check the padded sleeve's dimensions. For bottles, inspect the stretch pockets against the size and shape you use rather than assuming any bottle will be retained equally well. Consider those items together with the main-compartment load so the fit check reflects an ordinary packed day.
Campus 26L versus Robson 30L
The Robson adds four nominal liters while listing the same sleeve and bottle-pocket categories. Identify which recurring items would use that extra room before moving up. Compare actual dimensions and layout too, because matching feature labels do not prove identical construction, and a twenty-six-liter bag may organize your load differently from a thirty-liter one.
