Big Agnes Copper Spur HV UL3 Long

The Copper Spur HV UL3 Long is the three-person version of the line in extended length — a 244 × 178 cm floor and 119 cm peak height give 4.09 m² of space, or 1.36 m² per person with three occupants. Two DAC Featherlite NFL poles (9.3 mm) pitch a freestanding double-wall dome, and a weight of 1,782 g (1,614 g minimum) works out to 594 g per person, a solid figure for a three-person shelter in the ultralight category. Both fly and floor use 15D nylon sharing a 1,200 mm waterproof rating, three vents plus rain gutters help with airflow and keep water away from the doors. Two vestibules totaling 1.67 m² (a 41% ratio to floor area) add storage, and the interior includes four pockets, a gear loft, a lantern loop, and a media pouch — features suited to longer stays on trail. Eight Dirt Dagger UL stakes and a single stuff sack round out the set.
