The opinion of Aventure Nordique

The Sea To Summit 3-season Alto TR1 tent is available in 4 versions:



  • Alto TR1 : mesh inner - Sil/PeU fly - grey

  • Alto TR1 Plus : full fabric inner - Sil/PeU fly - green

  • Alto TR1 Pro : mesh inner - Sil/Sil fly - blue

  • Alto TR1 Plus Pro : full fabric inner - Sil/Sil fly - blue


Mesh Inner : It allows for better ventilation of the tent and saves weight. This room is very well suited for use in summer and in hot and dry environments.


Full fabric inner : It offers better protection against the elements. When the wind blows, it avoids the draught effect, and when the temperature drops, it allows a gain of a few degrees. It is equipped with mesh ventilation windows for use in hot weather.


Sil/PeU fly : PeU (polyether) has a longer service life than the traditional PU (polyurethane) coating.


Sil/Sil fly : Silicone on both sides of the fabric offers better tear resistance and greater durability than PeU. It also provides a small weight saving.


The Alto TR1 is a pure 1-person tent with a large interior volume. Its upper Tension Ridge pole in the shape of outstretched wings provides a large door and offers a generous volume to the passenger compartment. Its dome structure is semi-auto-suspended. In order to achieve a minimalist weight, the tent has slightly smaller dimensions at ground level.


The extended wings also eliminate the risk of condensation as much as possible with an efficient ventilation system. The tent has a high and low ventilation, provided by the underside of the outside doors so that the air can circulate well. Depending on the weather conditions, they can be opened or closed.


Its assembly is simple and fast. It is also possible to install only the double roof to get a big shelter, or only the room for nights under the stars. When it rains, the double roof can be installed first.


The storage cover can be divided into several compartments, so that the room can be separated from the double roof when the double roof is still wet. It is designed to be used as a storage pocket in the tent and as a ceiling lightbar (in combination with the lamp).


As an option (sold separately), it is possible to purchase a "Lightfoot" footprint covering the room or a "Bigfoot" footprint covering the room and the apses.
