Get more tent space for the weight when backpacking with your crew.

Popular, well-maintained campsites just don't scratch your itch for wilderness, so you pack up the four-person, three-season Big Agnes Copper Spur UL4 Tent (UL stands for ultralight), and set up camp well away from any roads, bathrooms, or RVs. Although it can't compete with a lighter-than-air one-person tent in the weight department, it weighs barely twice as much as the one-person Copper Spur, and sleeps four without any problem, making it an ideal choice for group or family backpacking trips where weight is still important. The Spur was designed with steep walls and a horizontal crosspiece for extra living space, and a Featherlite DAC hub-style pole system for easy assembly. It also has plenty of creature comforts (for a tent, anyway) like eight mesh pockets, individual media pockets with cord ports, and two large vestibules that comfortably hold packs, boots, and smelly gear, so your happy tent doesn't deteriorate into a pile of stink. 

The Spur also has mesh walls designed to circulate air and let you sleep under the stars when the weather's good, and a ripstop nylon fly with zipper-covering storm flaps and taped seams, ensuring that no water ends up dripping onto your face or soaking your bag. Two doors eliminate the need to stomp over your tent partners' gear and faces, and reflective guylines and webbing take some of the fear out of walking around the campsite in the dark. You can even pitch the Spur using just the poles, fly, and footprint (sold separately) if you're looking for an even lighter setup.

  • Two doors and vestibules
  • Steep wall design for extra headroom
  • Media pockets with cord port

  • Reflective guylines and corner webbing

Here's what others have to say...

Is this the newer version of this tent? (2014+)

What is the difference between Packaged Weight, Trail Weight and Fast Pitch Weight (Fast Fly Weight as Big Agnes calls it).

Also what does the footprint weigh?

Best Answer

Here is how Big Agnes defines the different weights for their tents:

Packed weight:

This is the heaviest you can expect your tent to weigh, straight out of the box or from the store. This weight refers to all packaging, hang tags, as well as the stuff sacks, fly, body, stakes, poles, and guy lines.

Trail weight:

This is the lightest you can expect your tent to weigh, stripped of everything but the essentials. This number reflects the weight of just the fly (no guy lines), body, and poles.

Fast-fly weight:

This is the weight of your fly, footprint and poleset only.

Copper Spur UL4 info:

Packed Weight - 5lb 12 oz (92 oz) or 2610grams

Trail Weight - 5lb 5 oz (85 oz) or 2410grams

Fast Fly Weight - 4lb 4 oz (68oz) or1930grams

Footprint Weight - 11 oz or 312grams

Desert Camping

  • Gender:Male
  • Familiarity:I've used it once or twice and have initial impressions

Used this yesterday for a family desert camp at the edge of the Persian Gulf. It was a bit windy with the spring shamal wind blowing. We got the tent up ok but the provided pegs did not hold in the sand. I changes them for some others I had with my sun shade and we had no problems. The tent was warm and well ventilated as the temperature fell during the night. I main use will be our holiday next year as we fly to camp in the south korea and hike in the mountains.


Awesome & Light

  • Familiarity:I've used it several times

This tent has been on backpacking trips and rafting adventures and has been a great addition to our outdoor gear. Its light and easy to set up, and of course I love the quality of Big Agnes gear. This tent kept us dry in multiple back to back rainy days and held up well in moderate winds.


Nothing Like It

  • Familiarity:I've used it several times

You will never be sorry you purchased this tent. Took it on the JMT for a week with three other guys, two of us are on the large size. All four of us fit with no problem, though we slept the "short" way, not the long way the Big Agnes diagram pictures. In other words, the 86" width allows all but very tall people to lay that way, and it gives four guys an extra 10" of shoulder room. One of the guys still had his pack above his head. The ample vestibules sheltered the other packs and our boots with no problem.

The weight-to-quality-and durability value of this tent cannot be beat. If you include the footprint (which you should), your total tent weight/person with four people is about 1.5 pounds/person. That's for near bomb-proof shelter.

The way the door is attached to the floor is odd, but you get used to it. I am sure there is a good reason for it, since Big Agnes puts much thought into their design. Love having the two doors and two vestibules.

Big Agnes' diagram shows people sleeping in it the "short" way. I think they intended this in order to eliminate crawling over one another to get out the door.
