We spotted these fairly unique inflatable tents at the Outdoor Fair in Germany. Start-up company Gentle Tent is making a range large-chamber inflatable structures which are good to be used for car or bike camping. With the exception of the Tipi (shown below) they all come with a single inflation chamber, and can be blown up using a foot pump (1-2 minutes) or a 12v pump (3-4 minutes).
The chambers are super strong and Gentle Tent have proven this by driving a truck over one of their own tents without damage.
Available in the UK once they get distribution sorted, but for now www.gentletent.com
