An excellent tent.
That being said, there is not a huge difference between that and the Nalo 2GT, other than a little bit of height and a bit of width. Where though there is a reasonably big difference is in the packed size, the Nalo being appreciably smaller and a bit lighter.
I was able to see the two tents in action, side by side, for a month. Of the two, I preferred the Nalo, for the reasons given above. There again, both were being used as ‘one man’ tents. A Nalo 2GT with three decent sized blokes in it would be, shall we say, ‘compact’.
I've had both and would say there quite a difference, obviously the size as a Kaitum 3GT is palatial and more importantly has 2 vestibules (Nallo has one!) and I found better ventilation.
