Manfrotto Tri Backpack M brand_Kessler 5 inches is for useDespite the name, the Manfrotto Tri Backpack M is only one backpack, not three of them. Unsure what makes this "Tri": There's a top compartment (measuring approximately 14x14x24cm) and a bottom compartment (about 15x22x26cm) but I'd assume a third compartment to complete the count, which this doesn't have. Maybe it's the laptop sleeve? Anyway, solid bag in excellent condition.
