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’.

​

Features

• Made for 3+ Seasons with a fabric inner tent which keeps out cold drafts. Plus a higher-specification waterproof floor, suitable for the wetter ground conditions.
• Tension Ridge raises the tent’s shape upwards for more usable head-and-shoulder space and creates a 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 to be waterproof by using premium materials including DAC poles, YKK zippers, 7-series aluminium 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 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 20D nylon tub floor is rated to 2500mm hydrostatic head – ideal for wet and boggy conditions.
• Lightweight 20D ripstop nylon inner tent fabric keeps out drafts and spindrift.
• 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.

Year-Round Versatility

Versatility that is head and shoulders above other shoulder-season tents

​

ENGINEERED FOR END-OF-SEASON WEATHER

• Dry setup and takedown (put up the rainfly first / take it down last to keep the inner tent dry)
• Quick Connect Foot System (attach the pole and the inner tent easily, even while wearing gloves)
• Fabric inner tent (prevents cold drafts from robbing you of warmth inside the tent)
• Uprated floor (waterproof performance for wet, boggy conditions)

​

PERFECT FOR WARMER-WEATHER USE, TOO

• Roll back the rainfly all the way to the Tension Ridge for stargazing, or redeploy the rainfly from inside the tent if the weather changes.

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.

Roland Tyson started making outdoor gear on an old industrial sewing machine in his childhood bedroom in 1983 at the age of 17.

As a young outdoor enthusiast, Roland had a passion and a talent for creating cutting-edge outdoor equipment for his own adventurers, and soon for other Australian adventurers. By 1991, after outfitting an unusual first ascent of Mt. Everest (a 1126+ kilometre, 8848 metres in elevation trek from sea level to a solo summit), Sea to Summit was born.

Roland’s drive to design the best, lightest and most durable equipment would take him farther into the remote Australian outback and eventually into the Himalayas. In these wild places, he could put his inventions to the ultimate test.

In 1993, Roland was joined by Penny Sanderson, who had spent six years at Australian Geographic. Her passion for exploration and innovation was a perfect fit for Sea to Summit. Penny and Roland began travelling several months out of each year, spending time climbing, sailing, trekking, overlanding and biking. Everywhere they went, they tested products and iterated design.

In 2022, Sea to Summit successfully transitioned from an owner-modelled business to a solid private equity backed business. The certified B-Corporation and Australian investment firm, Five V Capital, signed an agreement with Sea to Summit to become the majority shareholder. This marks an important milestone in Sea to Summit’s history as the brand becomes a global player in the outdoor industry, continuing to grow and expand.

Roland and Penny’s fundamental love of travel and design will see them remain active in Sea to Summit designing perfect gear for customers to enjoy and experience worldwide. The partnership will allow Sea to Summit to execute its growth plans in areas such as e-commerce, supply chain and sustainability expertise.
