Why We Like The ALTO TR1 PLUS Tent

The ALTO TR1 PLUS Tent is an obvious choice for our ultralight backpacking needs because unlike other ultralight tents, it’s designed with roomy livability in mind. Alto is the Italian word for “high”, which perfectly describes the spacious interior height that allows you to enjoy making breakfast in your tent each morning without feeling cramped. This member of the ALTO lineup is specifically designed for cooler temperatures, so the rainfly supplies excellent weather protection and the PU-coated full-fabric walls stand up to gusty conditions.


  • Featherweight backpacking tent puts an emphasis on livability
  • Polyurethane coated rainfly keeps you and your belongings dry
  • Apex vent at the peak of the tent strategically ventilates
  • Quick-connect poles make for easy setup and packing
  • Tension ridge pole design keeps the walls taught for quietness
  • Spacious vestibule lets you keep boots and gear outside
  • Semi-freestanding design allows for simple setup

Ultralight protection from ALL of the elements

In my quest to lighten my pack I’ve experimented with several shelter options: lightweight freestanding one-person tent, hammock and tarp, UL tent set up w trekking poles. But I had yet to find a solution that was lightweight AND provided protection in a wide range of weather. I think I’ve finally found the answer. The Alto TR1Plus is semi freestanding, so one collapsible pole plus stakes give it structure and ample headroom. I love that I can set up the fly first to keep me dry as I set up the tent itself — and take down my tent under the fly (and keep it dry!) on wet mornings. Lots of configuration options provide ample ventilation, even with the thicker inner fabric of the Plus. (Which I expect will let me actually be — dare I say? — comfortable in winter weather!) I will be putting this tent through its paces in my upcoming thru-hike of the Vermont Long Trail, during this epically rainy summer. I expect it will keep me dry all night, even if I’m soaked all day.
