This is when I've been using the Lunar Solo, Six Moon Design's flagship ultralight one-person tent. The Lunar Solo is single-wall, single-pole tent intended to be pitched with a trekking pole. Overall I found the Lunar Solo to be plenty spacious for one person with gear. The rear of the Lunar Solo has a 6-inch mesh portion between the floor and the main wall that helps with ventilation. But it did convince me that the Lunar Solo needs either a trekking pole or a heavier tent pole than the ultralight pole Six Moon Design provided.
