My husband has a Virga that he bought right before he met me. We've actually used it quite a bit for two people. I haven't used a Contrail, but I would think the interior space is similar. You really can't avoid bumping the sides a lot, and usually at least one person ends up with part of their sleeping bag against the wall as we move around in our sleep. We can fit our packs at the foot of the tent, but anything we leave out of the pack at night ends up on the mesh sides and might get wet in rain or heavy condensation. It can work if these things won't cause any major problems for you.
