User Review: Hilleberg Nallo 2
Four season only if you pitch it carefully.
We have the earlier equal hoop design.
This tent is very versatile: the outer goes up first and last which is great for rain; the floor pulls back so you can move about inside doing stuff away from the inner; the front porch ties back in a variety of configurations; inner can remain with outer for quick pitching of both.
I found the floor fabric to be a bit thin and had to repair a few holes, though these were probably made during a quick evacuation during a storm when a pole snapped (poles are now DAC and not the crappy Easton type).
Personally, I think of this as a very good, lightweight four season, where weight is more crucial than all round mountain safety: tunnel designs just don't have enough stability, relying too much on the anchoring of pegged guylines, and are disturbing to watch if you are a light sleeper.
The poles are (or were) a bit too long in the sections for two-wheeled touring.
No condensation problems beyond the norm. Order some longer pegs with the tent to secure the four side guylines.
According to Ethical Consumer magazine (July/August 2006), Hillebergs are made in Sweden (bar the poles) according to Swedish labour laws and receive a best buy rating generally. If this still applies then you can rest in peace knowing that no overworked children have made your shelter.
