Sea To Summit Alto Tent

Terms and Conditions

The one-person, semi-freestanding Alto TR1 is where ultralight tents meet class-leading space and comfort for three-season adventures. Our patent-pending Tension Ridge Architecture means this tent has unmatched useable room, a high ceiling, an oversized door and a large vestibule 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. Though the Alto TR1 weighs only 938g | 2lb 1.1oz (minimum trail weight), it’s packed full of intuitive features, like our FairShare Storage System, which is comprised of dual-use storage bags that can be clipped into your tent to create extra storage and our illuminating Lightbar. With its mesh inner and DAC’s world-class Featherlite NFL and PRESSFIT pole sections, the ultralight Alto TR1 is primed for fast-and-light solo exploits.
