When every gram matters on the trail, the Big Agnes Copper Spur UL2 delivers ultralight performance without sacrificing the comfort that turns a good adventure into a great one. At just 1.18kg trail weight, this freestanding backpacking tent sets up quickly on any terrain without requiring corner stakes, making it your reliable shelter whether you're camping on rocky alpine ledges or soft forest floors. The revolutionary HyperBead™ fabric technology provides 25% better waterproof protection while being 6% lighter than traditional materials, so you stay dry without the weight penalty. Dual side-entry doors and generous vestibules mean you and your tent partner can come and go independently while keeping your gear organized and protected, while the comprehensive ventilation system with high and low vents ensures you wake up refreshed instead of damp. This is the tent that serious backpackers choose when they refuse to compromise between ultralight efficiency and multi-season reliability.
