Is the Big Agnes Copper Spur UL3 the best 3-person tent on the market today? Learn why we think it is!

Big Agnes is a company that has become known around the globe for their high quality tents. Their products are tough, protective, long-lasting, stylish, and comfortable. That's a whole lot of goodness.

And when you combine all that with an ultra lightweight design and roomy interior, you get something approaching greatness. And that's the Big Agnes Copper Spur UL3.

Big Agnes Copper Spur UL3 Tent Review

To read the blurb on the company's website about the origin of the Copper Spur's name, you'd think this might be a product to stay away from.

It's said to be named after a copper mine that was nothing much more than a publicity stunt--it opened to widespread acclaim, but never yielded anything, not even a single patent.

Even if that is why you named your tent the way you did, why would you ever tell that to prospective consumers?

Fortunately, marketing and publicity aren't Big Agnes' strongest points. Their real strength comes out in the design and crafting of their camping tents.

The CS-UL3 is roomy enough for three people, it has a mesh ceiling for great star-gazing on fair-weather evenings, and it features two doors so you don't have to climb over your fellow campers to get out when nature calls your name in the middle of the night.

In short, we think it's one of the best 3-person tents out there. And even if it's not--even if some other model has got it beat by a fraction of an advantage--it's still more than worth your time to investigate further.

The general rule of camping tent buying is that you should get a shelter that's made for one more person than you plan on sleeping next to, making sure that you have enough interior room.

So if you have two campers in your party, you should get a 3-person tent, for example.

Well, there are three reasons why you wouldn't necessarily do this:

  1. You're camping with a loved one you don't mind snuggling up next to
  2. You and your fellow camper are of a smaller stature
  3. You buy a Big Agnes tent

This isn't a palace, no, but the Copper Spur UL3 is a 3-person tent that can seriously hold 3 people. Comfortably. And everyone at REI agrees.

This structure is also nice for camping in colder climates. You can be sure you'll stay warm with the rain fly on and the doors zipped tight.


It's one of life's hardships: if you want a higher quality product, you have to spend more money. For the Big Agnes Copper Spur UL3 (an undoubtedly high quality product), you have to be willing to part ways with about $350. And that's a lot of money. For many people, it's far too much money.

While the tent itself is an absolute wonder, the included accessories aren't necessarily the best. Specifically, the stakes that come with the Big Agnes Copper Spur UL3 don't have a lot of oomph in them. Campers around the world have complained of their Big Agnes stakes not going into hard earth or snapping off during set-up. This is an easy fix--just buy some aluminum replacements--but annoying all the same.
