While looking for a light weight tent I came across a UK maker of camping equipment.http://www.vango.co.uk/vango-airbeam-tent.html
Now far be it from me to be sceptical about someone's invention but I can't see how it could stand up in a strong breeze. Vango are fairly well known (in the UK) so I am interested as to how this works.
I am also inherently lazy so anything that makes putting up the tent easier is a winner in my books. Definatley a 12v job though. Non of those manual pumps for me.
