In reply to rhoppen:
Most likely it would also be OK...
But then again, I prefer to have room inside the tent... When the site hit's the fan, it's nice that you can keep yout stuff inside and still have room to cook...
But I haven't been on Aco, only Norway (winter and summer) and Alps.
BTW. I would still think about I-tent instead of hilight.
That said, my friends had no problems using a Firstlight in Patagonia...
