We had extra selected a 3 man tent since my junior ever slept with a buddy in a 2 man tent, which would have been but better suited for one person.
In this tent, I also think that it is close to 3 man EHR. For 2 people (each 1,68m tall) it was perfect!
When it rains, we have not tested it, so I can not write anything to the water tightness.
The reduction was also relatively easy. It forms a 8 and folds the two halves of 8 together. Then the same thing again and you can already push the envelope in it again!
We are very satisfied with this tent and would buy it again at any time! Can not recommend it more.
