I've been camping since the 90s and this is hands down the nicest tent I've pitched. The HyperBead fabric shed a heavy overnight rain without a single damp spot inside. Setup took me maybe 10 minutes solo, and my wife was genuinely comfortable — she usually complains about tent camping. Worth every penny even before the discount.
Took this on a week-long trip in the Sierra. Vertical walls make it feel way bigger than most 4-person tents, and two of us plus gear was luxurious. Only knock: the vestibules are a bit tight for full packs. Weatherproofing was flawless.
Split four ways, this thing is nothing in the pack. Two of us carried it on a 5-day traverse and never thought about the weight. Freestanding design saved us on rocky ledges where stakes were impossible. Stormed on us the second night — bone dry inside. Easily the best purchase of the season.
Quality is clearly there and the fabric is impressively waterproof. First setup took us almost 25 minutes figuring out the pole orientation and guy lines. By day three we had it down to 8 minutes. Would have loved clearer instructions, but once dialed in it's excellent.
Bought this for family trips with two teenagers. Both kids gave it the seal of approval — 'it doesn't feel like a tent, it feels like a room.' The HyperBead coating beads water off like a rain jacket. We've had three storms and zero leaks. Setup is quick enough that even the kids volunteer now.
Dry in a downpour, light, fast to pitch. No complaints.
Loved this tent at first — light, roomy, weatherproof. Then the main door zipper started splitting on our third trip, leaving a gap that let in mosquitoes all night. Big Agnes warranty has been responsive so far, but for this price I expected better hardware. Bumping to 2 stars pending the repair.
I'm a light sleeper and usually every breeze sounds like a hurricane in a tent. The Copper Spur's fabric is remarkably quiet and the structure barely flexes in wind. My knees appreciated standing up to change at my age — the near-vertical walls are a game changer. Docked a star because the stuff sack is a snug fit after packing.
Coming from an old dome tent that weighed a ton, this feels like cheating. Set it up at 8,500 ft in gusty conditions by myself — the freestanding hub design is intuitive and rock solid. Vestibule space handled two packs and boots. Condensation management with the two doors open is excellent. Highly recommend for anyone who hikes to camp.
