The Big Agnes Tumble 1 MtnGLO Tent utilizes LED lighting to make camping more comfortable and convenient than ever before. Instead of haphazardly dangling your headlamp from the top of your tent, patent pending mtnGlo tent light technology evenly illuminates the interior so you you can go over maps, read your book, or organize your gear for an early departure without being blinded by one harsh source of light. Powered by any USB source or three batteries, the lights are operated by a simple push button controller to turn them on, off, or to a mellow 50% setting. The LED light strand is integrated into the tent seams and is flexible and durable enough to endure repeated pitching and stuffing. Big Agnes built the Tumble 1 mtnGlo Tent's body out of sturdy ripstop material and the fly and floor out of fully taped, PU coated fabric for reliable, long lasting protection against the elements. Large mesh panels offer sufficient ventilation in summer's warmer weather, while the single door, single vestibule, steep wall construction and cross over pole design improve the interior living space. Multiple mesh and media pockets round out this tent's creature comforts to make you feel right at home out in the backcountry.
