Alto one-person is a semi-freestanding tent perfect for the weight-conscious solo 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.
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
Will a 200 x 64 cm pad fit in this tent?
You can just squeeze a large rectangular pad into the Alto TR 1 (it was primarily designed for ultralight backpackers who generally use smaller pads).
Worth the weight difference over a bivy shelter?
We think so. The Alto gives you room to sit up, excellent ventilation (so almost no condensation) and a vestibule to store wet gear - all of which you won't have in a bivy shelter.
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.
