Copper Spur UL3 mtnGLO® Specifications
mtnGLO® Light System
The integrated mtnGLO® system lights your tent's ceiling from a switch — no fumbling for your headlamp or wandering camp to find your tent. The mtnGLO system runs on standard batteries (check the included light hub for the battery type); simply replace them when output dims.
Fabric and Structure
- HyperBead® fabric: lighter, stronger, and more waterproof than standard ripstop
- High-volume freestanding design: ample interior room and stability through rough nights
- 3-person capacity: sleeps three with room for gear
UL3 mtnGLO vs Current Copper Spur HV UL3 mtnGLO
The older Copper Spur UL3 mtnGLO and the current Copper Spur HV UL3 mtnGLO share the same award-winning platform and mtnGLO lighting; the HV (High Volume) version increases interior volume and refines the pole structure. The pre-HV UL3 mtnGLO is absolutely worth buying on sale — at $99.91 vs $699.95, you get the same core tent and lighting for a fraction of the price. mtnGLO lights cannot easily be retrofitted into a non-mtnGLO UL3, which makes this factory-equipped model the smart buy.
