Franco: I'm not trying to prove you wrong or otherwise start an argument; I'd second your advice to look at the Moment. However, in your post, you say that the end and top vents go a long way toward reducing condensation. You also say that they can be closed, too. I'm curious: if you have to close them, it will usually be in conditions where you also have to close the vestibule door - and you've now eliminated most of the ventilation in exactly the conditions most likely to produce condensation. Any experience in how much condensation is generated in adverse conditions with the Moment buttoned up?

Again, I'm not trying to fault the Tarptent design; it might be an excellent alternative to the Seedhouse our poster is considering. My own experience is that any tent, single or double wall, buttoned up, is going to generate condensation, usually in large quantities. I'm wondering if the buttoned up Moment generates less than other tents you've used.
