Top-class materials built for daily use

The Alto TR1 1 man tent from Sea to Summit has a Tension Ridge Architecture (abbreviation: TR). This ensures you have more usable floor space and it offers great headroom thanks to the high ceiling. The tent also features a large vestibule in which you can stow away your equipment and protect them against the elements.

As for the Alto TR1’s materials, the tent floor and flysheet are made of ultralight ripstop nylon, while the inner tent is made of an air-permeable mesh polyester that wonderfully ventilates. Optimal protection against moisture and humidity is provided by the material's hydrostatic head of 1200 mm, the sealed seams and the silicone and polyether polyurethane (Sil-PeU) coating on the flysheet. As a result, the tent can withstand intense and persistent rain during your trek, hill walk and backpacking trip.

In addition, the Alto TR1 is supported by a lightweight, extremely tough frame made of anodised DAC Featherlite NFL and Pressfit aluminium. And, the easy-to-use Quick Connect Tent Feet allows you to adjust and attach the flysheet with just one hand.
