They do look a lil small but for the weight of a duo you could carry it for one man tent easy enough but id be concerned about conensation from the looks of it to me. Any thoughts on that?
Any single wall tent like these (and my beloved tarptent) will have condensation issues. With the tarptent it is about the pitch. I use a stick at the foot end to bring it up, and I sleep with the door open unless it is raining.
