If you camp right to the end of shoulder seasons, the Telos Plus two and three-person freestanding tents could be your shelter of choice. It offers the same easy setup and ingenious functional details as the standard Telos, with the ‘plus’ of materials that will keep you warm and dry in windier and wetter conditions. And across all seasons, it provides greater usable space, better ventilation and more versatility than any other lightweight tent in its class.
Tension Ridge architecture delivers a better space-to-weight ratio than any tent in its class.
The gold standard in tent poles — our tents combine DAC Featherlite NFL, NSL and PRESSFIT sections.
The poles of the Tension Ridge™ are swept upwards like the dihedral wing of an airplane – not angled downwards as is common in tents. This raises the tent’s shape, providing significantly more head and shoulder room, higher doors, easier access and more usable vestibule space.
Typical of Sea to Summit’s commitment to refining details to make gear frictionless and more functional, these machined aluminum clips make setting up the rainfly (either with the inner tent, or with a footprint in ultralight configuration) quick and easy. And they are far more durable than plastic buckles.
Every Sea to Summit tent packs up into three stuff sacks to allow you to split the load easily. During setup, two stuff sacks transform into gear storage pockets, while the pole stuff sack (with a translucent diffuser) becomes a Lightbar™. Add a headlamp or two for soft illumination throughout the tent.
How it started
"When we decided to take on ultralight backpacking tents, I knew who I wanted to collaborate with—master tent maker Jake Lah.
Jake is the father of modern tent architecture, and his company DAC produces some of the best aluminum poles in the world.
Both of us are driven by producing something better than what’s already out there—and I think we’ve achieved that with our ultralight backpacking tents.
The Alto and Telos deliver exceptional height and space—and are loaded up with unexpected features like adjustable venting and our unique Hangout Mode. They are, quite possibly, the most livable ultralight backpacking tents out there."

Frequently Asked questions
Is a footprint necessary with this tent?
The Telos Plus features a very waterproof (4000mm) floor, so it can be used in wet conditions without a footprint.
How is a PeU coating different from a PU coating?
PeU coatings are ether-based. They are much less susceptible to hydrolysis (which is when a urethane coating absorbs moisture and becomes soft or 'sticky', often in storage), so they're better for rainflys and tent floors.
Does '3+ seasons' mean it can handle snow?
While the Telos tent is designed for use up to the end of shoulder seasons, it's not built to withstand heavy snow loads and should be guyed out in winds above 20 mph.
