Editor’s Conclusion
Big Agnes is a company committed to sustainably-made, high-quality outdoor gear. The Big Agnes Copper Spur HV UL4 lives up to those standards.

There have been previous versions of this tent, but in my opinion, this refreshed version is a 3-season backpacking tent built with spaciousness and comfort in mind.

It is well-praised on many gear lists due to its superior design and upgraded features, such as off-the-floor storage and awning-style vestibules.

Although I noticed it is on the heavier side compared to other backpacking tents, the Big Agnes Copper Spur HV UL4 remains appealing because of its weather-resistance and easy setup.

Key Features

The Brand

Big Agnes was founded in 2000 with the goal of inspiring love for the outdoors and making that experience enjoyable. They are located in a northwestern Colorado ski town, testing and innovating their gear authentically. Also, Big Agnes is striving to make its gear sustainable in efforts to minimize its impact on the environment. That way, outdoors lovers can continue to enjoy nature for many generations.

Upgraded Features

The Big Agnes Copper Spur HV UL4 really shines when it comes to its upgraded features. This fresh version of the original has 2 doors, and the double-zipper vestibules have an awning that is perfect for warmer backpacking trips. It gives you a couple of access points for extra convenience. You can relax comfortably under the awning, and luckily, the setup is quite simple. It combines a stakeout loop with pole-tip capture, as well as a rainfly attachment for optimal stability, and this is done with its distinctive TipLok Tent Buckle.

Another aspect that I really enjoy is the extra storage space provided. The ceiling is already taller than most backpacking tents, increasing the overall volume substantially, and the large ceiling pocket gives you additional space. Plus, it has off-floor storage, giving you enough space to sleep well while still giving you options to put your belongings.

One more thing to mention is the low-condensation vestibule doors. They help regulate airflow within the tent, giving your backpacking experience a boost in breathability.

Space and Weight

The Big Agnes Copper Spur HV UL4 is commendable in its spacious size. It is a 4-person tent with a total floor area of 57 feet squared. The floor dimensions are 96 by 86 inches. This tent also has a peak height of 50 inches, allowing ample space for family or loved ones to sleep comfortably on backpacking trips.

As far as weight goes, it does not necessarily excel. It is definitely on the heavier side as a 4-person tent, so if you don't need the extra space, opt for the 2-person version. It comes in at a trail weight of 5 pounds 3 ounces, but the packed weight is 5 pounds 11 ounces.

Before you decide to take this tent backpacking, consider the weight of your other gear. You don't want to get dragged down by overly heavy gear.


The Big Agnes Copper Spur HV UL4 is marketed as an ultralight backpacking tent. It is certainly compact and can fit easily inside your pack with the rest of your camping gear. However, despite its upgraded features, this 4-person version of the Copper Spur HV may be on the heavier side for some people, especially if you're not accustomed to the added weight.

If you're going on a longer trip, perhaps consider a smaller option of this tent. You want to keep your gear as lightweight as possible when backpacking.


Overall, the Big Agnes Copper Spur HV UL4 lives up to Big Agnes standard. It is clear the company is constantly trying to perfect its gear for optimal use. The 2-door, 2-vestibule system, along with its improved storage, and ripstop nylon coated in waterproof polyurethane make it a waterproof tent and a durable option for most backpackers.

However, the price point may deter some users to look for a more affordable option. This tent is definitely on the more expensive side, and that may not be a reasonable choice for those shopping on a budget. Still, if you have the funds and are willing to carry a little extra weight while backpacking, the Big Agnes Copper Spur HV UL4 is a viable option.
