What Our Gearhead® Experts Are Saying:"I’ve used both sizes on mixed-weather trips, and the interior space is unreal for how light the tent is. The Tension Ridge really opens things up, and the updated Apex vent keeps condensation under control. Setup is intuitive, even when I’m tired and chasing daylight."We look to the Telos Evo when our routes demand an ultralight shelter that doesn’t sacrifice liveability. Sea to Summit builds these tents around the Tension Ridge architecture, lifting the tent’s peak upward and pushing the walls outward to create a taller, more open interior. Whether we’re turning the TR2 into a lightweight home for two or stretching out in the TR3, the space feels airy and functional in a way most ultralight shelters don’t manage. Upgraded vents with waterproof zippers and closable scoops help us manage airflow when humidity climbs, while the refined rainfly fabric sheds moisture and dries quickly after storms. With multiple pitching options—full protection, hangout mode, or fly-only—the Telos Evo series adapts to sun, wind, rain, and shifting climates across long miles of desert, forest, or mountain terrain.
