Sea To Summit Alto TR1 Plus

Ultralight solo tent with a high degree of livability for shoulder-season use

The Sea to Summit Alto TR1 Plus semi-freestanding tent provides maximum livability 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.

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

EXTENDED-SEASON VERSATILITY
Fabric inner tent and higher-specification waterproof floor will keep out cold winds and wet weather.

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.
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.

Construction & Materials:
— The 6” 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 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.
