The Sea to Summit Alto TR1 1-person tent combines ultralight backpacking with first-class space and comfort for three-season adventures.
The Tension Ridge architecture sets new standards: more usable space, a high ceiling and therefore more headroom, an oversized entrance for easier entry and exit and a large vestibule for storing equipment. Effective and adjustable ventilation at the zenith and several setup modes also make this backpacking tent the epitome of comfort and versatility.

Highlights:
- Tension Ridge lifts the shape of the tent upwards to create more usable head and shoulder space
- color-coded, ultra-strong and lightweight DAC NSL pole set and Quick Connect Pole Feet ensure easy assembly
- FairShare Storage System: The tent can be stowed in 3 bags to share the load
- For dry assembly and disassembly, the rain cover can be installed beforehand
- To extend the life of your tent floor, we recommend using a Sea to Summit tent footprint, available separately
- The 15 cm deep tub floor made of 15D nylon is designed for a water column of 1200 mm
- Apex ventilation – at the highest point of the tent, this oversized ventilation efficiently removes warm air
