Balancing weight with liveability, the Sea to Summit Alto TR1 is made for adventurous backpackers heading deep into the bush. 

This ultralight tent offers impressive comfort for modest specs: weighing in at only 1.1kg and packing down to just 10x46cm. Featuring Sea to Summit’s revolutionary Tension-Ridge architecture, the Alto offers incredible headspace and tall doors for easy entry, so that you can truly feel at home out in the wilderness. With a colour-coded and quick connect ultra-strong poleset, setting up has never been easier after an exhausting day of hiking. 

Keeping you sheltered from downpours, the Alto is seam-taped with a PeU-coated rainfly and a 12000mm hydrostatic head nylon tub floor, and the rainfly can easily be set up first to keep the inner dry in wet conditions. It’s comfortable in warmer weather too, with Apex Vents at the highest point to increase airflow and reduce condensation. Roll back the rainfly to gaze at the stars on a clear night, and then replace it easily from inside the tent.

The Alto TR1 is the ultimate solo backpacking tent for three-season adventures above the treeline.
