Xtherm noise isn't that bad and you only really hear it when getting on/off your pad.
I feel like the noise is contained inside the tent. Your not sending out a distress signal.
Turning in the middle of the night its much less noisey. And let's be honest if your turning in your sleep, your not really ASLEEP, so the noise isnt gonna pull you out of REM anything.
My first night I usually can't sleep much if at all. After the 1st full day of, hiking, climbing, hunting ect I'm usually sleeping like a corpse for the rest of the trip.
