- Tension Ridge raises the tent’s shape upwards for more usable head-and-shoulder space and creates truly higher doors for easier entry and more vestibule storage.

- Made for longevity and superior waterproof performance by using premium materials including DAC poles, YKK zippers, 7-series aluminium hardware and seam-taped rainfly.
- FairShare storage system: tent packs into 3 stuff sacks to split the load. After set-up, stuff sacks transform into gear storage pockets.
- Lightbar: add a headlamp and secure the tent pole storage sack to the apex of the tent for soft even illumination.
