     The Alto TR1 Plus semi-freestanding tent is the perfect choice for the active solo backpacker who'll camp right up until the shoulder seasons. It offers vertical walls, a tall, oversized door, and the same functional details as the standard Alto. Furthermore, it is crafted with materials that assure protection from strong winds and heavy rains. For those who travel solo, the Alto provides an unprecedented level of comfort and versatility which goes far beyond what ultra-lightweight tents normally offer.

    • Made for 3+ Seasons with a fabric inner tent which keeps out cold drafts. Plus a higher-specification waterproof floor, suitable for the wetter ground conditions.
    • Tension Ridge raises the tent’s shape upwards for more usable head-and-shoulder space and creates a truly higher doors for easier entry and more vestibule storage.
    • Color-coded ultra-strong lightweight DAC NSL poleset and quick connect pole feet make for easy setup.
    • Made for longevity and to be waterproof by using premium materials including DAC poles, YKK zippers, 7-series aluminum hardware and seam-taped PeU-coated rainfly.
    • FairShare storage system: tent packs into 3 stuff sacks to split the load. After set-up, stuff sacks transform into gear storage pockets.
    • Lightbar: add a headlamp and secure the tent pole storage sack to the apex of the tent for soft even illumination.
    • Rainfly can be setup first for a dry setup and takedown.
    • Includes 9 Ground Control Light Tent Pegs. 
    • 4 detachable guylines which can be quickly attached to loops on each tent corner.
    • To extend the life of your tent floor we recommend using a Sea to Summit footprint - sold separately.
    Construction & Materials
    • The 15 cm deep 20D nylon tub floor is rated to 2500mm hydrostatic head – ideal for wet and boggy conditions.
    • Lightweight 20D ripstop nylon inner tent fabric keeps out drafts and spindrift.
    • Silicone / Polyether Polyurethane-coated 15D nylon rainfly fabric provides long-lasting waterproof performance with a hydrostatic head. 
    • The poles of the Tension Ridge™ are swept upwards – not angled downwards as is common in tents. This raises the tent’s shape, providing significantly more livable space.
    • Apex Vent - at the highest point of the tent, this oversized vent efficiently expels warm air to prevent condensation and can be easily zipped shut from inside the tent.
    • Baseline Vents allow you to control airflow and effectively manage humidity and condensation in wet conditions without letting the rain in.
    • Quick Connect Foot is a beautifully designed, machined aluminum clip that attaches the pole and the inner foot with ease and is stronger than plastic buckles that can break.
