Hi Diane,
If you’re getting the tent wall close to your face on the lower side, it could be that (1) the pitch isn’t tight enough and the wall is hanging or, or (2) you should slide down away from this corner to leave it as a place for gear.
As the FAQ explains, the headroom is different on each side where one side has a lot of extra headroom while the other side is more normal. This ‘lower’ side has less head room but still should be reasonable to sleep the same way. Â When you’re laying down, the head clearance even on the lower side should still be more than the Duplex, like this:

One of the keys here is that the X-Mid Pro 2 is longer inside the fly than the Duplex, so you shouldn’t be centering yourself in the tent but rather sliding down to leave the low corner as a place for gear. When you do that it puts both people in a very normal side by side position (because the floor is parallelogram shaped) and head clearance should be reasonable on that side, like this:

With that said, the headroom on the other side is really generous so when two people share the tent it is best to put the taller person on the side with the extra room. You can sleep opposite so both people get the extra room, but we don’t think this is needed unless both people are quite tall.
