The Copper Spur HV UL2 MtnGLO Tent from Big Agnes combines its innovative LED light system with a lightweight design that any backpacker can feel good about putting in their pack. MtnGlo technology is an LED lighting system sewn into the upper seams of the tent that is powered by three AAA batteries (batteries not included). Once on, the lights create a nice mood lighting that's ideal for rigging gear, playing games, checking maps, or getting that perfect tent glow shot.
