Description

The Alto TR1 is a 3-season tent for 1 person from Sea To Summit.  With a mosquito net chamber to improve ventilation and make the tent lighter, this is the ideal tent for ultralight trekking on rather hot and dry terrain. 

TheAlto TR1 is an ultra-light tent which features the Tension Ridge architecture to give you more space, more height, more ventilation for more comfort! The tent also benefits from a vestibule to store all your gear

Its FairShare storage system allows you to evenly distribute the weight in your backpack.
The tent has two vents for optimal ventilation. They can be adjusted from the inside of the tent to cope with all weather conditions 

TheAlto TR1 has 5 setup options for more versatility. The Dry Set-Up allows you tu install the flysheet first. The Fly Only is the flysheet setup only, the Inner Only is the chamber setup only. The Partial Fly refers to the partial flysheet setup and finally, there is the classic tent setup. 

In addition, the Lightfoot and Bigfoot groundsheets are compatible with this tent to make it even more durable and comfortable!

An ultra-light and comfortable tent to accompany you on all your adventures!
