The Sea to Summit Alto TR 2 Plus is a top-of-the-line two-person tent designed for outdoor enthusiasts seeking lightweight and durable shelter. Built with adventurer’s needs in mind, this tent combines innovative features, high-quality materials, and user-friendly design to create the perfect companion for any adventure.

With a focus on lightweight construction, the Sea to Summit Alto TR 2 Plus is made for backpackers and hikers who value a low pack weight. Weighing in at just 3.9 pounds (1.8 kg), it is one of the lightest two-person tents available on the market. This exceptional portability is achieved through the use of premium materials and careful design choices.

The tent’s outer shell is constructed from 15D Ultra-Sil® Nano fabric, known for its incredible strength-to-weight ratio. This fabric is not only lightweight but also highly durable, providing long-lasting protection against the elements. The floor is made with 40D nylon, offering excellent waterproofing and abrasion resistance for added peace of mind.

Setting up the Sea to Summit Alto TR 2 Plus is a straightforward process, thanks to its color-coded clip construction system. This intuitive design allows users to easily assemble the tent, even in adverse weather conditions. The DAC Featherlite® NFL poles further contribute to the ease of setup, providing exceptional strength while maintaining a lightweight profile.

Comfort is not compromised in the Alto TR 2 Plus. The tent’s spacious interior provides enough room for two occupants, with a floor area of 31.4 square feet (2.9 square meters). The innovative design maximizes livable space, including dual vestibules that offer additional storage for gear or shoes. The incorporated Dry Door system keeps the interior protected during entry and exit, preventing rainwater from entering the tent while you come and go.

Ventilation is essential for a comfortable camping experience, and the Sea to Summit Alto TR 2 Plus excels in this department. The tent features a large door and two side mesh panels that promote cross-ventilation, maintaining a cool and fresh interior even in warmer climates. The mesh panels are strategically placed to limit condensation and increase airflow, ensuring a comfortable night’s sleep.

Weather protection is a top priority for Sea to Summit, and the Alto TR 2 Plus has been engineered to withstand a variety of conditions. The tent is equipped with a 10,000mm-rated waterproof fly, effectively shedding rain and snow. All seams are tape-sealed to prevent any water leakage, and the bathtub-style floor design provides an added layer of protection against ground moisture. With its sturdy construction and excellent weather resistance, this tent is suitable for use in a wide range of environments, from warm summer nights to cold and snowy adventures.

To enhance its versatility, the Sea to Summit Alto TR 2 Plus also comes with a range of optional accessories. These include a footprint to protect the tent’s base, a gear loft for convenient storage, and a repair kit for on-the-go fixes. These extras allow users to customize their setup to suit their specific needs and make the most out of their outdoor experience.

In conclusion, the Sea to Summit Alto TR 2 Plus is a top-tier two-person tent that offers exceptional portability, durability, and comfort.
