Big Agnes Cooper Spur UL2 Long and UL3 Long are 96" long. IME, UL2 works best for 1 person/squeeze 2 people and UL3 works best for 2 people.

Too bad you didn't ask last summer. In July 2024, we bought a 3UL Long for $425, gave it as a wedding gift to a son of a climbing/skiing bud and the son's new wife. They use it as a 2-person with a dog. The husband is 6'0" and there's sufficient room for the dog to sleep at their feet. I am not aware of a lightweight double-wall backpacking tent with that much interior length. We have an old (2003?) Stephenson (now Warmlite) 3R which is quite long inside, especially if used by only 2 people. We replaced it a couple years ago, and I would consider selling it for very cheap ($100 plus shipping; new is $1,400). If you haven't seen one: The single-wall vestibules at each end are open, creating useable interior length of est. 100" with 2 people. It has had lots of use and looks a bit rough, but it kept us dry in some nasty high elevation storms the last year we used it. It has a very long footprint, although we always found a way to pitch it. It's not freestanding, but pitches fine on a slab using rock anchors in paracord loops. I replaced the zippers and sewed guy line anchors to the apex of the pole sleeves, which makes it a very stormworthy tent in up to 80mph winds (i.e., too windy to stand up outside the tent). AFAIK, Warmlite tents are the most stormworthy tents for the price. FTR, Warmlite tents are not for everyone and require some experience to get the most out of them, e.g., the single wall ends invite condensation in some conditions, but we always managed it with a Shamwow. Initiate a chat if you're interested. If you're spooked about buying a 22 y.o. tent for $100, I fully understand. My wife, my buds and I are aging out of high mountaineering routes, and I would like to get our old 3R into the hands of a younger mountain traveler on a budget.

I'm in no rush to sell it. I've had some great adventures using that tent.

Although they may not qualify as ultralight, Big Agnes UL2 XL and UL3 XL have 96" of interior length, and they are quite lightweight for freestanders.

Definitely 3. I have a Big Agnes Copper Spur 3 long and it’s the perfect size for my wife and I and our clothes, etc

I have the BA Cooper Spur and it held up like a CHAMP during 30 mph winds while on the Lost Coast Trail, this last May. Ironically it did end up needing patching from that same windstorm but only because the big rocks I piled on over the stakes ended up poking holes in the rain fly, but I'm chalking that up to my own stupidity in not paying closer attention to jagged edges. I know nothing about ultra lightweight gear so my opinion probably isn't worth much, but figured I'd chime in anyway. Happy hunting!

I'm your size, have a Durston xdome 1+, used it 5nights so far. Weighs 1kg and actually fits 1person comfortably. They had some issues with the carbon poles the first year though, but I think they've fixed that now. It will also come with an aluminum pole option soon. Big Agnes Copper Spur LONG tents will fit, but heavy and not so good in bad, windy wet weather in my experience. Tarptent Rainbow is semi freestanding and also would fit you. Those are just the ones I have used so far...

I would buy another copper spur, and in fact have over the years starting with the UL3, then HVUL3, and now HVUL3 long. Love the tents. Good size for me and my now 6'+ teenage son who was i think 2yo when he first slept in one. I took the HVUL3 Long to Philmont last summer for just myself. Oh the luxurious room! 😀 The only issue I've had is the shock cord deteriorated after a number of years, but I bought a spool off Amazon for $20 and restrung the poles for the first 2 tents. Pretty easy.

We have a HV UL 3 Long, which we got so our dogs can sleep at our feet. So far, we really love it, and despite being bigger than the tent it replaced (2015 Half Dome 2+), it is actually lighter. As for durability, we've managed to tear the stuff sack halfway open, in the first year of use. No offer of warranty replacement when I contacted BA. Outside of that, it is intuitive, roomy, light, and has decent storage.

I was in the same boat- and I found a great deal on the Big Agnes CopperSpur. If you are in the US they still have one for $354- it’s a $950 tent. https://a.co/d/313YPa2 You can almost stand up inside- it’s huge!

Another vote for the CopperSpur. I have the 3 p version for 2 people and it’s perfect.

I'm 1.90 and have been in both of these. Pretty similar really: can fit but need to be careful. Which is better than most trekking tents to be fair. When my hubba hubba died (after many years!), I shelled out for a long version of the Big Agnes copper spur. Much more comfortable but not great in strong winds supposedly
