Big Agnes equipped the Tumble 3 mtnGlo Tent with LED lighting to making camping more convenient than ever. Patent pending mtnGlo tent light technology brightens up the interior evenly so you don't have to play cards or sort gear with one glaring beam hanging above you. You can power the LED lighting by any USB power source, and the included controller requires batteries. Big Agnes built the Tumble 3 mtnGlo Tent's body out of burly ripstop, and the fly and floor out of fully taped, PU coated fabric for reliable, long lasting weather protection. Large mesh panels offer sufficient ventilation in summer's warmer weather, and two doors, two vestibules, and mesh and media pockets complete your camping conveniences.
