Alto TR1 - One Person Ultralight Tent

$449.00-$449.00

Description

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.

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 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 aluminum hardware and seam-taped PeU-coated 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.
4 detachable guylines which can be quickly attached to loops on each tent corner.
To extend the life of your tent floor we recommend using a Sea to Summit footprint - sold separately.

Construction & Materials

The 6” 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 dark grey color 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 livable 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 aluminum clip that attaches the pole and the inner foot with ease and is stronger than plastic buckles that can break.

Tension Ridge architecture delivers a better space-to-weight ratio than any tent in its class.

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

SET-UP GUIDE

Frequently Asked questions

Will a 79 x 25" 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.
