Alright boomer, I think I found something you might be interested in.
I was looking for something for myself to solo use, when I ran across Mountain Laural Designs (MLD). The DuoMid with solo insert would run 1.5lbs., and have a nice large vestibule area, but then I was thinking, it would be kinda tight (no room for gear) for Kathryn and I in it with the 2 person insert.
So, they have a SuperMid! I could get that, a solo insert and a 2 person insert, so depending on if I'm by myself or with Kathryn, I can take either insert I need.
With solo insert it would weigh 31oz. (2lb.), and with the 2 person insert it would only weigh 2.5lb.!
I would have tons of room for two people, and when I'm by myself it would be a palace!
Check it out, it might just be what you're looking for in a two person shelter, and it's light enough to still take for solo trips with the smaller insert.
In fact, with the 2 person insert it still weighs less then the solo shelter you have now!
