The Sea to Summit Alto and Telos tents feature a unique Tension Ridge architecture, which differs from the traditional design where tent brow poles angle down. Instead, the Tension Ridge is an antenna-like structure that angles up, allowing for a higher ceiling height without increasing the footprint. This design creates near-vertical walls, higher doors, and more space.
In addition, the Tension Ridge design enables the placement of vents at the highest point of the tent, improving ventilation and reducing condensation.
