Hilleberg says about the Nammatj 3
The Nammatj and Nammatj GT are the masters of both high and low country, equally suited for a high altitude expedition or a weekend walk in the local hills. These robust all-season, all-arounders pitch quickly and easily, can be taken down and moved in a flash, yet are far stronger and lighter than any other tent in their class.
Because of their superb strength to weight ratio and compact footprints, both the Nammatj and Nammatj GT have become immensely popular with extreme users, such as polar travelers looking to save weight, mountaineers doing remote routes in the highest ranges, professional guides, and military special forces teams. But these same characteristics are just as highly prized by more “regular” users, as well: backpackers, cycle and paddle tourers, and anyone needing maximum strength while reducing weight.
