Alto TR2 two person is a semi-freestanding tent perfect for weight-conscious backpackers who still want a high degree of liveability 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
Tension Ridge architecture delivers a better space-to-weight ratio than any tent in its class.
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.

Frequently Asked questions
Do I need to use a footprint with this tent?
The Alto has a very light floor, waterproof to 1200mm. It can be used on wet grass/undergrowth without a footprint. However, a footprint will protect the floor from damage on abrasive surfaces.
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.
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).
