All about this product



The two-person, semi-freestanding Sea to Summit Alto TR2 Plus with full fabric inner, is where ultralight tents meet class-leading space and comfort for cooler climates. The patent-pending Tension Ridge Architecture means this tent has unmatched useable room, a high ceiling, oversized doors and two large vestibules for storing gear. A truly effective and adjustable ventilation system and multiple set-up modes also make this backpacking tent the epitome of comfort and versatility.

Designed for cooler climates, the breathable full fabric inner blocks wind while allowing humid air to escape. Though the Alto TR2 PLUS weighs only 1274g (minimum trail weight), it’s packed full of intuitive features, like the FairShare Storage System, which is comprised of 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 TR2 PLUS is primed for fast-and-light cool-climate exploits.
