The g20 ion is a spacious, lightweight, two-person, three-pole semi-geodesic tent that is ideal for camping and travels around the world. Having a higher-cut fly and large mesh panels on the inner, it is optimised for warmer climates. (You might find it cool in more wintry conditions.) Although the flysheet is sufficiently water-resistant for four-season use, its high-cut baseline means the inner is more vulnerable to splashing in hard rainfall. The g20 ion is very light and easy to pitch, and the porch area is reasonable, but those wanting more storage or cooking space can choose the larger vestibule version – click here for the g20 ioniX
