Description
The Alto TR1 Plus semi-freestanding tent provides maximum liveability for the solo backpacker who is active right to the ends of shoulder seasons.
Vertical walls, a tall, oversized door and the same functional details as the standard Alto combine with materials that will keep you warm and dry in windier and wetter conditions. Whenever you camp, you’ll have more usable space, better ventilation and more versatility than any other ultra-lightweight tent – because ‘going solo’ shouldn’t feel like ‘solitary confinement’.
DESIGN DETAILS
Tension Ridge architecture delivers a better space-to-weight ratio than any tent in its class.

TECHNICAL FEATURES
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.
Mounted at the highest point, Apex Vents allow warm moist air to escape and channel fresh air into the tent. The vent can easily be zipped shut from inside the tent and does not require mesh to retain its shape, significantly improving airflow. Baseline Vent allows you to control humidity in wet conditions by opening or closing lower portion of the door while maintaining vestibule function and rain protection for your gear.
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."

Frequently Asked questions
What are the differences between regular and 'plus' models?
The Alto Plus has a nylon fabric inner (with unzippable vents) rather than mesh to prevent cold air getting into the inner tent. It also has a more waterproof floor (2500mm against 1200mm).
Does '3+ seasons' mean it can handle snow?
The Alto is not designed to shed heavy snow loads - it is intended for use up to the ends of shoulder seasons but not winter. An Alto should be guyed out in winds above 20 mph.
What does 'semi-freestanding' mean?
The Alto tents have a lighter poleset than the Telos, but need to have the corners staked out at the head end.
