The Big Agnes Rattlesnake SL 2 mtnGLO tent is an excellent balance of weight livability and durability. The tent is even equipped with its own built-in lighting making it an excellent option for 3-season backpacking.

Stretching a full 88" in length the interior of the Rattlesnake SL 2 mtnGLO tent is 52" wide at the head and tapers to a width of 42" at the feet. With 27 square feet of interior space and a trail weight of only 3 pounds 9 ounces the tent can serve as a comfortable home for two hikers or as a sprawling shelter for one. Dual vestibules offer 18 square feet (9 square feet per vestibule) of additional weather-protected external storage space. Two interior mesh pockets provide places to stash gear and clothes while media pockets located above the sleeping area enable headphone/ear bud cord routing from phones or other devices. Integrated gear loft loops offer a connection point for the Big Agnes Wall Gear Loft (sold separately). The tent is also compatible with the Big Agnes Entertainment Loft and the Powercase/Loft with Joey T55 (also sold separately).

Offering enough light to effectively illuminate the interior of the tent patent-pending mtnGLO technology integrates a strand of LED lights directly into the tent seams. Durable and flexible the strand holds up to the wear of pitching and tearing down. A simple push-button controller allows you to toggle through on off and 50% brightness settings. The light is powered by 3 AAA batteries (not included) but can also be lit by any USB power source.

The Rattlesnake SL 2 mtnGLO tent's DAC Pressfit aluminum poles are lightweight and durable. The single hub/pole design works in conjunction with the tent body's integrated clips to make pitching the tent fast easy and intuitive. An additional short section of pole runs across the roof of the tent pulling the tent body taut increasing the verticality of the interior walls and helping to maximize the spaciousness of the two vestibules.

Ample mesh on the tent body and the dual doors encourages cross ventilation and provides circulation to fight condensation build-up. Coated with 1200mm waterproof polyurethane the rip-stop nylon floor and rainfly are lightweight and durable. All of the tent’s seams are seal-taped with waterproof solvent-free polyurethane tape (no PVC or VOCs) to further protect the tent from the elements. If you want to travel lighter leave the tent body at home and use the rainfly alone with the optional Rattlesnake SL 2 mtnGLO Footprint (sold separately) for a tarp-style set-up that weighs a mere 2 pounds 14 ounces.
