Sea To Summit Alto TR1 1-Person Ultralight Tent

A one-person, semi-freestanding tent, the Alto™ TR1 is perfect for the weight-conscious solo backpacker who still wants a high degree of livability in their shelter.

Alto’s revolutionary Tension Ridge™ architecture allows for taller oversized doors and vertical walls that create an unrivalled amount of space. Apex Vents™ positioned at the highest point of the tent effectively expel moist air and minimize condensation, and the variable rainfly can be rolled back on both sides for stargazing, then deployed quickly from inside the tent.
