Sea to Summit Alto TR1 Plus

Technologies and manufacturing processes

• TENSION RIDGE

  The poles of the Tension Ridge are bent upwards like the wings of an airplane - and not tilted downwards as is usual with tents. This raises the shape of the tent and offers significantly more head and shoulder room, higher doors, easier access and more usable vestibule space.

• QUICK-CONNECT POLE FEET

  Typical of Sea to Summit's commitment to refining details to make gear smoother and more functional, these machined aluminum clips make setting up the rain fly (either with the inner tent or with a footprint in ultralight configuration) quick and easy. And they are far more durable than plastic buckles.

• FAIR-SHARE STORAGE / LIGHTBAR

  Each Sea to Summit tent packs into three stuff sacks so you can easily share the load. During pitching, two packsacks convert into gear bags, while the pole packsack (with a clear diffuser) becomes a lightbar. Add one or two headlamps to gently illuminate the entire tent.

• APEX VENT / BASELINE VENT

  The Apex Vents located at the highest point allow warm, moist air to escape and direct fresh air into the tent. The vents can be easily zipped closed from inside the tent and do not require mesh to maintain their shape, greatly improving airflow. Baseline Vent allows you to regulate humidity in humid conditions by opening or closing the lower part of the door, while maintaining the function of the vestibule and rain protection for your gear.
