That's all verily well above the dew point or in the dry, but as soon as hot warm air hits cold plastic you get condensation. The best tent I have read about is the pyramid design with the vent right at the top. Hot air rises!
Aye I suppose your right, 'cause it's always warm and sunny in Scotland so I never had problems.
The cover vent at the top of the door on the MKII onwards which will allow the hot air out.
One of the end vents; also covered, to allow airflow.
Sweden where they're designed has weather that's pretty similar to Scotland for a lot of the year. Cold and wet, or driech as we say 'round here. They openly say that you'll get condensation unless you take action, it's why all their tents have good venting systems that also defeat the rain.
My current Hilleberg is the Tarra which has it's big top vent covered in it's own fly, allows good through flow of air.
