Sea To Summit Alto TR1

Ultralight solo tent with a high degree of livability

The Sea to Summit Alto TR1 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.

MORE SPACE
Tension Ridge™ creates best-in-class interior space & higher doors for unmatched livability.

UNMATCHED VERSATILITY
The rainfly can be rolled back for stargazing, then secured quickly from inside the tent.

SUPERIOR VENTILATION
The Apex Vent™ expels warm air & Baseline Vents allow you to control airflow to prevent condensation.

DESIGN DETAILS
Lightbar™, FairShare Storage System & Quick Connect Foot System make tent life easier.
• 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 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 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.
