>>1484758As others have stated, hammocks will be uncomfortable with two people in them regardless of size. It works if you lay on top of each-other.
That being said, I sleep in a "double" hammock every day and wouldn't want to go down in size again. I only take a smaller UL hammock for camping, but it's still bigger than your normal 1 person camping hammock.
If you want to have a big one, you can just buy any camping hammock that is 3x2m, doesn't matter what company. I've bought some expensive brand ones, some cheap ones from amazon and ali, and there was no difference in quality or material at all.
