Most of the two-man tents I've looked at won't hold two men except if they are spooning. Not really what I was looking for. Both the BA FC UL2 and the Kilo are a tight fit for sure. They can call them what they want to, but really they are palace's for one or good for a couple kids. The FC UL3 is good for two adults and that's what I have. It was 3.66 lbs as shipped to my house. I dropped a few stakes, guy lines, and stuff sacks and got the weight down to 3.49 lbs. It is surely above your weight limit, but will fit two people with a little room left over. The package is fairly small for a freestanding tent and you could split it between two people to spread the weight out.
If your still looking to go to the two-pound range, you can get close using a tarptent from SMD, TT, or Lightheart. But even those are a few ounces over including stakes, guylines, etc.
I was really stuck on a 2-lb. shelter option trying to keep my base weight low. But after allot of research, I bought the lightest (freestanding) tent that would hold two people, regardless of the name. Maybe next years tents will actually hold two people. Hope you find something that will work for you.
