Sea to Summit Alto TR1 Plus Tent

The one-person, semi-freestanding Alto TR1+ backpacking tent combines generous space with ultralight comfort in cooler climates. Sea to Summit's Tension Ridge Architecture offers extended useable room, a high ceiling, an oversized door and a large vestibule for storing gear. With a truly effective and adjustable ventilation system and multiple set-up modes, this backpacking tent offers outstanding comfort and versatility.

Designed for cooler climates, the breathable full fabric inner blocks wind while allowing humid air to escape. Though the Alto TR1 PLUS weighs only 1056g (minimum trail weight), it’s packed full of intuitive features, like the FairShare Storage System; dual-use storage bags that can be clipped into your tent to create extra storage, and the illuminating Lightbar. With a full fabric inner and DAC’s world-class Featherlite NFL and PRESSFIT pole sections, the Alto TR1 is primed for fast-and-light cool-climate solo exploits.
