Description
Alto two-person is a semi-freestanding tent perfect for the weight-conscious backpacker who still wants a high degree of livability in their shelter.
The revolutionary Tension Ridge architecture of the Alto allows for taller oversized doors and vertical walls that create an unrivalled amount of space. Apex Vents positioned at the highest point of the tent effectively expel moist air and minimize condensation, and the variable rainfly can be rolled back on both sides for stargazing, then deployed quickly from inside the tent.
‘Alto’ is the Italian word for ‘high’. One night will prove that the Alto is a level above other ultralight tents.
DESIGN DETAILS
Tension Ridge architecture delivers a better space-to-weight ratio than any tent in its class.
Technical Features
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.
Powerhouse Collaboration
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."

SET-UP GUIDE
Frequently Asked questions
What are the differences between regular and plus models?
The Alto Plus tent has a nylon inside fabric with unzippable vents rather than mesh to keep cold air from getting into the inner tent. The Plus model also features a more waterproof floor (2500mm against 1200mm).
Does '3+ seasons' mean it can handle snow?
While the Alto 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.
What does 'semi-freestanding' mean?
Rather than needing to secure a tent with poles attached to every corner, a semi-freestanding tent may only need one pole to hold up the structure and reinforced with stakes at the corners. Semi-freestanding tents are lighter weight and have smaller packed-volume.
Our Alto tents have a lighter poleset than the Telos, but they need to have the corners staked out at the head end.
