Integrated MtnGLO overhead lighting sets this spacious, freestanding three-person ultralight tent apart on trail
The Big Agnes Copper Spur UL3 MtnGLO is the tent for groups who want a genuine three-person shelter without the weight penalty that usually comes with it. With 41 square feet of floor space and 43 inches of head height, three people can actually sit up and move around. The HyperBead rainfly and floor shed weather without intentionally added PFAS, and the solvent-free polyurethane taped seams keep the construction free of PVC and VOCs. On shoulder-season trips when nights run long, the mtnGLO light and the dual 11-square-foot awnings mean the tent works as a real basecamp, not just a place to sleep.
What Our Gearhead® Experts Are Saying:
"With three people sharing one tent, nobody's passing a single headlamp back and forth or waking someone else while digging through a bag by feel. The overhead light covers the whole space, so whoever's up long after everyone else is asleep can find what they need without disturbing the other two."
