The Big Student is the highest-capacity pack in this group. JanSport specifies 34 litres (2100 cubic inches), external dimensions of 17 x 13 x 7.5 inches, a weight of 1 lb 7 oz (0.65 kg), and a recycled 600 denier polyester body. Two features separate it from the rest: two full main compartments rather than one, and a dedicated 15-inch padded laptop compartment with its own zip, sized for a machine up to 15.5 x 12.5 inches. Add the front organiser panel with key clip and two exterior zippered stash pockets and it is the only pack here designed around a genuinely full timetable, where books, a laptop and daily items each need somewhere separate to live. Against the 32 litre Main Campus it gains 2 litres and half an inch of depth; against the 26 litre SuperBreak Plus it carries 8 more litres at 0.25 kg more weight.
HOS lists this as the full-course-load option. The most common student bag mistake is buying for an average day and then overfilling it every week, and this is the model sized for the heaviest day rather than the typical one.
Secondary school and university students carrying multiple textbooks plus a laptop on a full timetable, who need the machine kept apart from the books.
Capacity encourages carrying more than you need, and 34 litres of textbooks is heavy regardless of how well the pack is built. Do not buy it if your daily load is a laptop and a notebook: at 17 inches tall it will look and feel oversized, and the SuperBreak Plus does that job at 0.4 kg. It is a school pack in appearance, not an office bag.
