About The Product
The Alto Bikepacking two-person is a semi-freestanding tent perfect for weight-conscious bikepackers and who still want a high degree of liveability in their shelter.
Sea to Summit’s engineers took the ultralight Alto TR2, equipped it with a poleset with shorter pole segments, and designed function-specific storage sacks to mount on your bike.
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
Please note: Due to the bikepacking concept, this tent does not contain a lightbar (like our other Alto tents).
Product Features
- 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.
- Color-coded ultra-strong lightweight DAC NSL two-hub poleset and quick connect alloy pole feet and C-clip make for easy setup.
- Made for longevity and superior waterproof performance by using premium materials including DAC poles, YKK zippers, 7-series aluminum hardware and seam-taped rainfly.

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."
-Roland Tyson, Founder & Head Designer at Sea to Summit
