I have not used it in that type of weather yet. I think you will always get some condensation in that type of water proof material However,that top cap is pretty loose fitting and it should help a lot.In real nasty weather though,you can seal it up pretty good.
They also sell an inner tent for them that supposedly does away with it.
Seek Outside put out a blurb on managing condensation.
