In reply to Alan Mc: My original (£14.99) got used for the first time on Lundy earlier this year. Stood up to 3 days of strong gusting winds and heavy prolonged rain. Only problem was damp coming through the groundsheet but no one else seems to have had a similar problem so I assume it was just a dodgy batch of groundsheet material.
I am thinking of picking up another for a new inner and spare poles/pegs. The orange colour is a bit useless for stealth camping but would be fine for campsites.
