If you are looking for a definitive Big Agnes Copper Spur HV UL 3 tent review, you have likely realized that finding a truly spacious yet lightweight backpacking shelter is a constant battle. Most ultralight tents sacrifice interior volume for weight savings, leaving you cramped and claustrophobic. On the other hand, comfortable tents are often too heavy to carry for miles into the backcountry.
The Big Agnes Copper Spur HV UL 3 tent is legendary because it promises to solve this dilemma. It claims to offer a palace-like interior with vertical walls and ample headroom while weighing less than many 2-person tents. It is marketed as the ultimate solution for backpacking trios, couples who want luxury space, or parents hiking with a child or dog.
But as we head further into 2026, with new competitors entering the market, does the delicate fabric hold up to real-world abuse? Is the high volume architecture genuinely effective in bad weather? And does it truly justify the premium price tag compared to cheaper alternatives like the Naturehike Cloud Up 2 or the more robust MSR Elixir 2?
In this in-depth Big Agnes Copper Spur HV UL 3 tent review, we are tearing down every feature of this iconic shelter. We will analyze the durability of the ultralight nylon, test the unique awning-style vestibules, and compare it against other top contenders.
Whether you are planning a thru-hike on the PCT or a weekend getaway in the Rockies, this guide will help you decide if the Copper Spur HV UL3 is the right investment for your 2026 adventures.
Quick Verdict
Ideally Suited For: Ultralight backpackers who want luxury space, couples who refuse to sleep shoulder-to-shoulder, and small families or pet owners needing a lightweight shelter that doesn’t compromise on livability.
The Bottom Line: Even in 2026, the Big Agnes Copper Spur HV UL 3 tent remains the gold standard. It masterfully balances weight, space, and features better than almost any other tent on the market. The high-volume design creates a massive interior that feels like a castle compared to standard backpacking tents.
While the materials are thin and require care, the performance-to-weight ratio is unmatched. If you can afford the investment and treat it with respect, it is arguably the best all-around 3-person backpacking tent available today.

The “HV” Difference: What High Volume Means for You
The “HV” in Big Agnes Copper Spur HV UL stands for “High Volume,” and it is the secret sauce of this tent’s success. Standard dome tents slope sharply from the center, meaning you can only sit up in the very middle. The Copper Spur uses a specialized pole hub (the “TipLok Tent Buckle”) and pre-bent pole sections to push the walls outward, creating a boxier shape.
This architectural shift means that the 43-inch peak height isn’t just a single point; it extends across a significant portion of the ceiling. Three people can sit up side-by-side without their heads pressing against the mesh. If you are used to the cramped quarters of a Naturehike Cloud Up 1 or similar solo shelter, the interior of the Copper Spur will feel cavernous.
This verticality also benefits the footbox. The walls at the foot end are steep, so your sleeping bag doesn’t rub against the tent wall. This prevents the dreaded “wet footbox” syndrome caused by condensation transfer, a crucial factor we discussed in our guide on how to stay warm camping in a tent.
Setup: Intuitively Designed for Speed
Pitching the Big Agnes Copper Spur HV UL tent is remarkably straightforward. Big Agnes uses a hubbed pole system where all the main poles are connected.
The Process
- Stake the Corners: Lay out the tent body (and the Big Agnes Copper Spur HV UL 3 footprint if you have it) and stake the four corners.
- Assemble Poles: Snap the single hubbed pole structure together. It forms a large “X” with a cross-bar.
- Insert Tips: Insert the pole tips into the proprietary TipLok Tent Buckles at the corners. These buckles capture the pole tip, so it doesn’t pop out while you walk to the other side, a massive help for solo setup.
- Clip Up: Attach the plastic clips on the tent body to the frame. The tent takes shape instantly.
- Add Cross Pole: Place the short cross pole across the top to spread the ceiling.
- Fly On: Throw the rainfly over, match the color-coded buckles (orange to orange, grey to grey), and tension it down.
The entire process takes less than 5 minutes for one person. It is significantly faster and less fiddly than threading sleeves on a Coleman WeatherMaster 6 or wrestling with the hubs of a heavy-duty tent like the Gazelle T4 Hub Tent.
Interior Livability and Comfort
What is it like to actually live inside the Big Agnes Copper Spur HV UL 3?
The Floor Plan
The floor is rectangular but slightly tapered (head is wider than feet). However, the width is generous. At 70 inches wide at the head, it easily accommodates three standard 20-inch pads or two wide 25-inch pads with room for a dog or gear in the middle. For a couple, this tent is a palace. You have room to sprawl, change clothes, and organize your pack without elbowing your partner.
Storage Revolution
Big Agnes revolutionized tent storage with this model. The “3D bin pockets” at the feet are massively raised pockets that utilize dead space. You can dump socks, electronics, and headlamps into them easily. There is also a huge media pocket on the ceiling with cord routing for headphones, allowing you to watch movies on a tablet during a rainstorm. This attention to detail makes long trips much more organized compared to a basic Coleman Sundome 4 person tent.
Awning Vestibules
The most distinctive feature of the current Big Agnes Copper Spur HV UL model is the awning-style vestibules. The vestibule doors have extra zippers that allow you to prop them up using your trekking poles. This creates a shaded porch area. It is perfect for cooking in light rain or simply enjoying the view while staying out of the sun. It expands the livable space of the tent beyond the mesh walls, a feature rarely seen on ultralight tents.
Weather Resistance: Ultralight but Storm Worthy?
We tested the Big Agnes Copper Spur HV UL 3 against wind and rain to see if the lightweight materials hold up.
Rain: The silicone-treated nylon fly with a 1200mm waterproof coating is highly effective. Water beads up and rolls off instantly. The seams are factory taped with solvent-free polyurethane tape (no PVC or VOCs). Even in sustained downpours, the interior remains dry. The bathtub floor rises high enough to prevent splashback, provided you pitch it on a well-drained site as recommended in our how to plan a camping trip guide.
Wind: The DAC Featherlite NSL poles are strong and flexible. They flex under wind load rather than snapping. The guy-out points are reinforced and velcro tabs connect the fly directly to the poles, adding structural rigidity. While it is not a 4-season bunker like the ALPS Mountaineering Tasmanian 2, it handles 3-season storms with confidence.
Condensation: The massive mesh body provides excellent ventilation. Even with the fly fully zipped, the airflow is sufficient to minimize condensation. The awning vents on the vestibules can be opened to create a cross-draft, further reducing moisture buildup.
Durability and Materials: The Ultralight Trade-Off
This is the most critical part of any Big Agnes Copper Spur HV UL 3 tent review. To achieve such a low weight, Big Agnes uses proprietary 15D and 20D nylon fabrics.
The Reality: These fabrics are thin. They feel like tissue paper compared to the heavy polyester of an Ozark Trail 6 person tent. They require care. You cannot pitch this tent on sharp rocks or sticks without a footprint. You should not let your dog scratch at the door mesh.
However, the “double rip-stop” weave increases tear strength significantly compared to older models. We found that while the fabric feels delicate, it is surprisingly resilient to tension and abrasion if treated with respect. If you are rough on gear or camp exclusively on abrasive granite, you might want a heavier tent like the MSR Elixir 2. But for the weight-conscious hiker who practices good campsite selection, the durability is sufficient for thousands of trail miles.
The Importance of the Footprint
We strongly recommend purchasing the Big Agnes Copper Spur HV UL 3 footprint. It is sold separately, which is a common complaint, but it is essential for protecting the thin floor. The footprint also enables the “Fast Fly” setup, where you pitch just the rainfly and footprint with the poles for an ultralight shade structure or emergency shelter.
Using a footprint will double the lifespan of your floor. If you don’t want to buy the official one, you can make your own from Tyvek, a tip we often share in our guides on how to clean a tent with mold and maintenance.
Comparison: Copper Spur vs. The Competition
To create a balanced Big Agnes Copper Spur HV UL 3 tent review, we must compare it to its top rivals.
Big Agnes Copper Spur HV UL 3 vs. MSR Hubba Hubba 3
The MSR Hubba Hubba is the closest competitor.
- Choose MSR if: You want slightly more durable fabrics (20D/30D mix) and a symmetrical pole structure that is arguably a bit stronger in heavy wind.
- Choose Big Agnes if: You want more interior volume, better pockets/storage, and the awning vestibule feature. The Big Agnes Copper Spur HV UL generally feels more spacious and “livable.”
MSR Hubba Hubba 3-Person Lightweight Backpacking Tent
Big Agnes Copper Spur HV UL 3 vs. NEMO Dagger OSMO 3
The NEMO Dagger uses a poly-nylon blend fabric that sags less when wet.
- Choose NEMO if: You hate sagging rainflies and want massive vestibule space (the Dagger has larger vestibules).
- Choose Big Agnes if: You want a slightly lighter tent with better interior pockets and the awning feature. The Big Agnes Copper Spur HV UL 3 is often preferred for its ease of setup.

Big Agnes Copper Spur HV UL 3 vs. Naturehike Cloud Up 3
The Naturehike is a budget clone.
- Choose Naturehike if: You are on a strict budget. It costs a fraction of the price.
- Choose Big Agnes if: You can afford it. The materials, warranty, pole quality (DAC vs generic), and architectural volume of the Big Agnes Copper Spur HV UL 3 are vastly superior. The Big Agnes is a long-term investment; the Naturehike is a budget entry point.

Real World Usage Scenarios
The Thru-Hiking Trio: For three hikers sharing a tent on the AT or PCT, the Big Agnes Copper Spur HV UL 3 is the dream. Splitting the weight three ways (poles, fly, body) means each person carries just over 1 lb. That is lighter than most solo bivy sacks.
The Luxury Couple: For a couple, this tent is pure luxury. You have room for wide pads, all your gear inside, and a dog. It offers the space of a car camping tent at a backpacking weight. If you are wondering what to pack when camping for a romantic backcountry trip, this tent should be top of the list.
The Solo Bikepacker: The short pole segments (when broken down) make this tent packable in bike panniers or handle-bar rolls. The massive interior space allows a bikepacker to bring panniers inside at night for security and dryness.
Maintenance and Care
To protect your investment in the Big Agnes Copper Spur HV UL tent:
- Use a Footprint: As mentioned, the Big Agnes Copper Spur HV UL 3 footprint is mandatory for longevity.
- Keep Zippers Clean: The lightweight zippers are precise. Dirt and grit will wear them out. Clean them with a toothbrush and water after sandy trips.
- Dry Thoroughly: Never store it wet. The silicone coating is durable but not immune to mildew. If you pack it wet, set it up to dry at home immediately.
- Patch Promptly: Carry the included repair tube and some Tenacious Tape. If you get a small puncture, fix it in the field before it becomes a tear.
Frequently Asked Questions (FAQs)
Yes. The fly and floor are silicone-treated with a 1200mm waterproof polyurethane coating. The seams are fully taped. It handles rain exceptionally well. However, because the fabric is lightweight nylon, it can sag slightly when wet/cold, so you may need to re-tension the guy lines before bed.
It is a 3-season tent. It can handle light snow (a dusting), but heavy snow loads will collapse the roof. The mesh body allows too much spindrift (blowing snow) to enter in a blizzard. For winter camping, look at our 3 season vs 4 season tent guide for better options like the ALPS Mountaineering Tasmanian 2.
Yes, it comes with 8 lightweight Dirt Dagger UL stakes. They are high quality but you might want to buy 4 extra stakes to fully guy out the tent and the vestibule awnings in windy conditions.
It is 20D nylon. It is thin. You need to clear your campsite of pinecones, sharp rocks, and thorns. Always use the Big Agnes Copper Spur HV UL 3 footprint or a piece of Tyvek/Polycro ground sheet.
If you backpack frequently and value comfort and low weight, yes. The engineering that goes into making a tent this big and this light is expensive. It is a piece of high-performance gear. If you only car camp, you can save money with a heavier tent like the Coleman Skydome 6 person tent.
Wrapping Up
The Big Agnes Copper Spur HV UL 3 is a marvel of modern backpacking engineering. It manages to be impossibly light while offering livable space that feels luxurious. The awning vestibules, 3D storage pockets, and high-volume architecture show that Big Agnes understands what hikers actually want: comfort without the weight penalty.
It is not a cheap tent, nor is it a bombproof winter bunker. It requires care and respect due to its ultralight materials. But for 3-season backpacking, it is arguably the best tent on the market in 2026. It hits the sweet spot of weight, space, and features perfectly.
If you are serious about backpacking and want a shelter that won’t weigh you down or fence you in, the Big Agnes Copper Spur HV UL 3 tent is the upgrade you have been waiting for. It is a purchase you will not regret when you are miles from the trailhead, dry, comfortable, and enjoying the view from your awning porch.
