Big Agnes Copper Spur 2P Review
I pulled into Horse Camp in the spring with a pack full of camera gear and one job left before the real work started: get the tent up before the wind picked up.
Horse Camp sits in that sweet spot on Shasta. High enough that you're not wasting a day hiking up from the parking lot, low enough that you're not exposed on the summit push itself. It's the obvious staging ground if you're going for the top, and it's exactly where I set up the Big Agnes Copper Spur UL2 for two nights as my base camp.

Pros
Doors on both sides makes entry and exit easy and keeps you from climbing over gear or a tent mate in the middle of the night.
Large interior pocket keeps small essentials like headlamps and gloves organized and within reach in the dark.
Spacious vestibule fits boots and gear under cover and handles rain without crowding the sleeping area.
Sized up for solo comfort — the two-person version gives a solo climber carrying extra gear, like a camera kit, real room to move and organize.
Cons
Dark fabric runs hot. Great for drying wet gear fast, bad for sitting inside during a sunny afternoon after a long climb.
Not built for serious alpine conditions. It held up in high wind on Shasta, but pushed close to its limit, and I'm not confident it would handle a heavy snow load on top of that.
Floor is vulnerable to sharp gear. My ice axe sliced it open. Keep pointed metal away from the tent, even when you think you're being careful.
Not a big-mountain tent. Solid for backpacking and moderate mountaineering base camps, but not something I'd trust on an Everest or Denali-level expedition.
I've used older versions of this tent for years. This is the updated model, and the update is a real one. I can't quote you the exact weight savings over the last version, but you can feel it the second you pick up the bag. For a three-season tent doing double duty as a mountaineering base camp, that weight matters. Every ounce on your back is an ounce you're not excited about above 10,000 feet.
Spring worked in my favor here. I was surrounded by snow but wasn't fighting it. No storms rolling through, no serious accumulation piling on the fly. That's an important distinction, because this is a three-season tent, not a four-season one. I wouldn't take it anywhere near an Everest or a Denali. It's not built for that kind of punishment, and it'll tell you so if you push it. I got a taste of that on Shasta itself, when the wind picked up hard one afternoon. The tent held, but I was clearly testing the upper edge of what it's designed for. Had real snow load been added to that wind, I honestly don't know how it would have handled it.
Inside, it earns its keep. Doors on both sides is one of those features you don't think about until you have it, and then you can't go back. No climbing over your tent mate, no unzipping the wrong side at 5 a.m. in the cold. The interior pocket is generously sized, which matters more than people think when you're organizing headlamps, gloves, and snacks in the dark. And the vestibule is big. Big enough that I could keep my boots outside the sleeping area but still under cover, and stash gear there without worrying about rain getting in.
That vestibule space, plus the interior room in general, is why I'd tell any solo climber to size up to the two-person version, even if you're sleeping alone. I was carrying a full camera kit on top of standard mountaineering gear, and having the extra square footage to lay things out, change layers, and actually move around made a real difference in comfort. Yes, you're carrying more weight for space you're not "supposed" to need. I'd take that trade every time.
The tent is dark, almost charcoal. That cuts both ways. Wet gear dries faster in there because it soaks up heat. But that same heat absorption makes it rough during the day. After a full day climbing, I wanted to sit down and recover, and the tent was too hot to be in. I ended up outside instead, which meant no real escape from the sun during the hottest stretch of the afternoon.
The fabric held up well overall, durable through two nights of use and a lot of gear getting shoved around inside it. The one exception was self-inflicted: my ice axe sliced open the floor. Lesson learned, keep pointed metal objects away from your tent walls. The upside is Big Agnes backs their gear with a strong warranty and repair program, so getting it fixed isn't a fight.

Bottom line:
The Big Agnes Copper Spur did exactly what I needed on Shasta, and I'd use it again for a similar trip. But I'd keep it in its lane. Backpacking, three-season trips, moderate mountaineering base camps like Horse Camp, that's where it shines. Push it into serious alpine conditions and you're outside what it's built for.
