About The Product

Alto one and two-person is a semi-freestanding tent perfect for weight-conscious backpackers who still want 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

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.
Colour-coded ultra-strong lightweight DAC NSL poleset and quick connect pole feet make for easy setup.
Made for longevity and superior waterproof performance by using premium materials including DAC poles, YKK zippers, 7-series aluminium hardware and seam-taped rainfly.
FairShare storage system: tent packs into 3 stuff sacks to split the load. After set-up, stuff sacks transform into gear storage pockets.
Lightbar: add a headlamp and secure the tent pole storage sack to the apex of the tent for soft even illumination.
Rainfly can be setup first for a dry setup and takedown.
Includes 9 Ground Control Light Tent Pegs and 4 removable Ground Control Guy Lines with custom attachment toggles.
To extend the life of your tent floor we recommend using a Sea to Summit footprint - sold separately.

Construction & Materials

The 15 cm deep 15D nylon tub floor is rated to 1200mm hydrostatic head – ultralight, waterproof and durable.
Ultra-lightweight 15D polyester mesh inner for maximum ventilation. Its green colour provides excellent visibility.
Silicone / Polyether Polyurethane coated 15D nylon rainfly fabric provides long-lasting waterproof performance.
The poles of the Tension Ridge are swept upwards – not angled downwards as is common in tents. This raises the tent’s shape, providing significantly more liveable space.
Apex Vent - at the highest point of the tent, this oversized vent efficiently expels warm air to prevent condensation and can be easily zipped shut from inside the tent.
Baseline Vents allow you to control airflow and effectively manage humidity and condensation in wet conditions without letting the rain in.
Quick Connect Foot is a beautifully designed, machined aluminium clip that attaches the pole and the inner foot with ease and is stronger than plastic buckles that can break.

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).
