In reply to newhey:
a couple of lads used one on the saunders last year.
i spoke to them in the morning to get more info about the tent.
they hadn't vented it enough and were quite damp - because of condensation caused by the single skin, not the rain.
it takes some careful pitching - get the tension correct in the pegs - too high or too low and it will sag in the middle.
the poles are glass fibre not alloy. replace these if you really want to save weight. (under a kg)
Add a vent panel (use midge net) underneath the cowl at the foot end of the tent to reduce condensation.
it is not the same bargain that the previous argos small tent was. it is not the same quality of design or manufacture.
