The Big Agnes Copper Spur UL 3 mtnGlo Tent brings LED lighting to the backcountry. Patent pending mtnGlo tent light technology brightens the interior evenly so you don't have to play cards or sort gear with one glaring beam hanging up top. You can power the LED lighting by any USB power source, and the included controller requires batteries. Big Agnes built the Copper Spur UL 3 mtnGlo Tent's body out of burly and light ripstop fabric, and it made 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 multiple pockets offer complete camping convenience.
