The f2 ultra combines ultralight and high-performance. Weighing in at an incredible 2.5 kg, it nevertheless offers all the weather-beating abilities of the full geodesic design. Thanks to the greater internal volume created by its four-pole structure, the f2 ultra also feels very spacious for a two-person tent, even though it only has the footprint of a t1 or g1. It is uniquely suited for mountain travel, wilderness trekking and lightweight expeditions where low weight and the ability to withstand bad weather are of the highest priority.
