One of our best-selling, full-featured, ultralight backpacking shelters, the Copper Spur HV UL series is designed with a high volume hub to maximize strength and increase living space without adding weight. Large dual zipper doors and steep wall architecture make backcountry trips with a smelly partner - or three - more comfortable than you may have thought possible. Our proprietary patterned double rip-stop nylon fabric is incredibly durable, to stand up to your biggest adventures.
