The one-person, semi-freestanding Alto TR1 is where ultralight tents meet class-leading space and comfort for three-season adventures.

The Sea To Summit 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 938 g (minimum trail weight—if pegs, guy ropes and pack sack are dispensed with), it’s packed full of intuitive features, like the Sea To Summit FairShare Storage System, which is composed of dual-use storage bags that can be clipped into your tent to create extra storage and the Sea To Summit illuminating Lightbar. With its mesh inner and DAC’s world-class Featherlite NFL and Pressfit pole sections, the ultralight Sea To Summit Alto TR1 is primed for fast-and-light solo exploits.

Features:
• Apex Vent: Vent at the zenith of the tent that efficiently dissipates warm air, reducing condensation build-up
