The semi-freestanding Sea to Summit® Alto TR1 Plus 1-Person Tent provides maximum livability for the solo backpacker who is active right to the ends of shoulder seasons. Vertical walls, a tall, oversized door and the same functional details as the standard Alto combine with materials that will keep you warm and dry in windier and wetter conditions. Whenever you camp, you'll have more usable space, better ventilation, and more versatility than any other ultra-lightweight tent––because going solo shouldn't feel like solitary confinement. The 6"-deep 20-denier nylon tub floor, rated to 2500mm hydrostatic head, withstands wet and boggy conditions. Lightweight 20-denier ripstop nylon inner tent fabric keeps out drafts and spindrift. Silicone/polyether polyurethane-coated 15-denier nylon rainfly fabric provides long-lasting waterproof performance with a 1200mm hydrostatic head. Apex Vent at the highest point of the tent efficiently expels warm air to prevent condensation and can be easily zipped shut from inside the tent. Baseline vents allow you to control airflow and effectively manage humidity and condensation in wet conditions without letting the rain in. Tension Ridge™ design raises the tent's shape upwards for more usable head-and-shoulder space and creates a truly higher doors for easier entry and more vestibule storage. Roll back the rainfly all the way to the Tension Ridge for stargazing or redeploy the rainfly from inside the tent if the weather changes. Color-coded, ultra-strong lightweight DAC® NSL pole set and quick-connect pole feet ensure easy setup. Premium materials engineered for longevity include YKK zippers and 7-series aluminum hardware. FairShare storage system packs the tent into 3 stuff sacks to split the load. After set-up, stuff sacks transform into gear storage pockets. Add a headlamp and secure the tent pole storage sack to the apex of the tent for soft, even illumination. Set up rainfly first for a dry setup and takedown. Sea to Summit Alto TR1 Plus 1-person tent includes 9 Ground Control Light tent pegs. 4 detachable guy lines can be quickly attached to loops on each tent corner.
