Equipped with an impressive set of features at an affordable price the 3-season worthy Big Agnes Tumble 3 mtnGLO tent offers reliable durability a roomy interior and even its very own built-in lighting system.

The internal dimensions of the Tumble 3 mtnGLO tent are 93" long by 73" wide. With 47 square feet of interior space and a trail weight of 5 pounds 13 ounces the tent can serve as a comfortable home for three hikers or as a sprawling shelter for two. Dual vestibules offer a combined 18 square feet of additional weather-protected external storage space. Four interior mesh pockets provide places to stash gear and clothes while two internal 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 Square Gear Loft Trapezoid Gear Loft Wall Gear Loft or Large Wall Gear Loft (all 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 Tumble 3 mtnGLO tent's 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 doors encourages cross ventilation and provides circulation to fight condensation build-up. Coated with 1500mm waterproof polyurethane the polyester 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 Tumble 3 mtnGLO Footprint (sold separately) for a tarp-style set-up that weighs just 4 pounds 3 ounces.
