The North Face's Terra collection consists of backpacks built for fun backpacking trips, and the Terral 40L Backpack is the smallest pack in that collection. Its 40L capacity is perfect for overnighters or weekends if packed correctly. Compared to traditional top-loaders, the Terra stands out with its full J-zip opening that zips down from the top lid to the backpack's bottom so you can access the entire main compartment from top to bottom. The floating lid lets you pack a tent or sleeping bag without taking up the pack's 40L capacity. This pack also features the Dyno Lift System, which is The North Face's comfiest suspension to date, with its self-equalizing shoulder straps and padded, ventilated back panel.
