Copper Spur HV3 Expedition

The Big Agnes Copper Spur HV Expedition is quite a sturdy type of tent, technically 3+ seasons and it is fairly lightweight. It can withstand strong winds and snow buildup. It’s not for real expeditions nor winter alpine conditions. It is a great choice for average wild camping imo.

My copper spur broke on me in a wind storm (granted it was very high wind on an exposed mountain). 2 of the 4 plastic buckles that the tent pole goes into at the end broke. Also my friend on the Colorado Trail broke 2 big Agnes tents this summer while setting up (once the tent pole bent/broke, other time I can't remember because I hadn't met them yet). I still think it's a good tent, but as a backpacker and mountaineer who cares a lot about weight, I probably wouldn't buy it again, I just don't quite trust it. Cleverhiker has very good points, but honestly thru hiking generally doesn't put you in a crazy exposed campsite like the top of a Scottish highland summit

Big agnes 3 person with 2 vestibules. Free standing tent, not too heavy.

My personal tent is a Big Agnes Copper spur 3 person that I got on sales at the end of the season. I use that for Scout events and backpacking. Our family tent is a Coleman 6 person we got at Costco. Sometimes I bring my old 2 person REI dome tent and stick one of the kids in that when we do family camping. The Cots fit in the Coleman. It's hard to set up the larger tent by myself, with a little help it is pretty easy especially not that my son is taller than me.

Big Agnes 3-person tents are hard to beat for weight, quality, and space.

Big Agnes 3P. They make several models. Do get the bigger tent, the 3P. You’ll be sorry if you don’t, particularly if the weather gets bad.

The BA Copper Spur is available in 3, 4, & 5 person sizes. note that the regular 3P is tapered and will only fit (3) 20" or mummy pads. There is a 3XL that will fit (3) 25" pads. I have the 3 MTN Glow which has built in lights. Highly recommend the entire series

Looking at the poles will tell you quite a bit about sturdiness. The Freelite 1 uses DAC NFL 8.7mm poles with a forked design. So one end of the tent has essentially 2 archs of 8.7mm while the other end has a single arch of 8.7mm. That would be comparable in sturdiness to other tents that also use a forked arch of 8.7mm, such as Big Agnes Fly Creek and Tiger Wall, and Nemo Hornet. Tents that use essentially dual arches of 8.7mm at both ends are going to be sturdier, like X-Dome 1+ but also BA Copper Spur, MSR Hubba, and many others. Easton Carbon 3.9 is very similar to DAC 8.7 mm in sturdiness. Then both brands of tent pole makers make numerous stiffer options but with higher weights that would likely put the tent over your 1 kg goal.
