We looked at these in Decathlon in Le Mans last year and I was really impressed with them. There is an inner tent and an outer and they seemed like they would stand up to some wet and windy weather. Then later in the year there was a young couple camped next to us in one in Epernay, we'd already remarked that it must be very cosy for two then they decided to get a little umm friendly one morning and you could see arms and legs poking out of the tent and the whole structure was moving fairly rhymically!!!
