Hilleberg Nammatj GT 3 Person Tent Kerlon 1800 outer tent fabric and 10 mm poles make for an exceptionally stable tent Pitching requires only four pegs, yet additional peg and guy line points - 14 on the Nammatj and 18 on the Nammatj GT - provide a myriad of options for increasing stability. Remarkably strong Spectra guy lines are attached to both the vestibule and back wall vents and at two points on all pole sleeves on both sides of the tent Both Nammatj and Nammatj GT have spacious interiors with full sitting height in most of the inner tent, one vertical inner tent entrance, and, thanks to the tunnel design itself, near-vertical side walls A single entrance and vestibule afford easy access and plenty of storage space, but keep the weight low. The Nammatj GT's extended vestibule provides even more storage space The entrance on the GT's extended vestibule boasts a full no-see-um mesh door (which can be zipped off completely), and a multi-slider zipper door that can be opened from the top, side, or bottom
