I ended up going for it and got the shelter I think it was the one with no front or ground sheet but still had the option to add a door and aground sheet thought I was being clever as it was on sale and ended up cheaper to buy the shelter and overwrap than it was to buy the whole bivvy and overwrap but I've only just got the overwrap and I ordered it in November last year. but have to say for the money it is brilliant quick and easy to set up just like the tempest only its nearly half the price and much better head room I'm 6ft and have no problems sitting down in it which is what put me off the tempest!!
