The opinion of Aventure Nordique

The Sea To Summit Alto TR1 is the mesh version of the Atlo range (also available in solid fabric). The mesh inner allows the tent to be ventilated and saves weight. This inner is very well suited for use in summer and in hot and dry environments.

The Alto TR1 is a 1-person tent with a large interior volume. Its Tension Ridge top pole in the shape of unfolded wings provides a large door and generous interior volume. Its dome structure is semi-self-supporting. In order to achieve a minimalist weight, the tent has slightly smaller dimensions in terms of floor space.

The spread wings also ensure that the risk of condensation is minimised with an efficient ventilation system. The tent has top and bottom ventilation, which is provided by the underside of the outer doors so that the air can circulate well. Depending on the weather conditions they can be opened or closed.

It is quick and easy to erect. It is also possible to install only the double canopy to obtain a large shelter, or only the inner for nights under the stars. When it rains, the flysheet can be put up first.

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

As an option (sold separately), a "Lightfoot" ground sheet covering the inner or "Bigfoot" ground sheet covering the inner and apses can be purchased.
