When you need more shelter than a bivy can provide but don’t want to lug around a full-fledged tent, there’s the Zero 1—one of the most exciting products from Korean ultralight company Zerogram. Built to accommodate the solo backpacker, this simple A-frame tent uses trekking poles to pare down weight, coming in at about a pound and a half. The tent has two doors, both lined with no-see-um mesh, and measures 6.8 feet long, 3.6 feet wide at its widest point, and 3.6 feet tall at its tallest point. While most of the tent is single-wall, ventilation is improved with a protected foot vent, the two doors and covered vestibule.
