The North Face designed the Womens Terra 40 Backpack specifically for all you trail divas covering a lot of ground in a day. The North Face placed this mid-sized backpacks shoulder straps closer together to accommodate a womans narrow shoulders, and shortened the torso length of the pack. The Terra 40 Backpack has an open-air mesh panel across the back, allowing airflow and cooling your back so you dont end up with a sweat-soaked shirt. Adjust the sternum strap and tighten The North Faces hip-belt to transfer weight away from your shoulders. For quick overnights, stash your bedding in the Terra 40s sleeping bag compartment.
