Thanks. I know many people love the Nallo, but I just can't get past this design flaw (as I see it). Not being able to adjust the vents from inside the tent, when condensation is such a potential issue... that's a major thing to me. Particularly as the Hillebergs are true 4-season tents (i.e. the fly comes down all the way to the ground), so proper venting is really important. The Nammatj models are the heavier version of this design, with the rear vent higher up and adjustable from inside. But the Nammatj 2 GT also weighs 3.5 kg:

I guess for me in the lightweight tunnel tents, the Kaitum looks good:

It has the benefit of two doors (so great through draft potential), vertical end walls, two vestibules. I find myself wondering if the one big vestibule of the Nallo GT would be better than two smaller vestibules of the Kaitum. The Kaitum 2 is 20cm longer than the Nallo 2 GT, so roughly the same amount of real estate.

This guy apparently used a Kaitum 2 solo on his GDMBR tour, and liked it a lot:
