The O2 Tent is The North Face's lightest tent for ultralight backpackers, alpinists, and weight conscious campers. At a little over a pound, the O2's superlight construction includes no see um mesh walls, and the ripstop fly and floor have PU coatings to protect you from cold winds and wet weather. The North Face equipped this ultralight tent with one large door and a vestibule big enough for all your backpacking gear. High low venting ensures airflow throughout warm summer nights. A vaulted head and footbox give you and your buddy a surprising amount of space, and The North Face added multiple loops for dry lines and headlamps. You can replace the end poles with your own trekking poles to reduce the O2's weight even more.
