I’ve had a pile of 2-man tents over the years. My wife and my favorite is the current BA Copper Spur HV UL2, made more wonderful by the offering of a subtle, non-eye-straining, mossy green color.
BA also has a pile of new tents that are even lighter, including a “Tiger Wall Platinum” which looks outstanding and is about 13oz’s less than the Copper Spur. The “normal” Tiger Wall looks great too, and with its more robust fabric, is still 9oz’s less the the Copper Spur 2P. I think there’s a diminishing return going lighter than something like the fabrics found on the regular Copper Spur or Tiger Wall.
I saw the Nemo Hornet 2P mentioned, and while the 1P is among my favorite solo tents, I find the 2P is a bit on the small side for a couple.
There are a lot of good choices out there these days…
