Can’t comment on the Kampa one but we have the Air 6 and it’s superb. Easy to put up and take down and the quality is way better than what we’re used too.
Depends on the price you pay though, we were lucky and got ours in a sale for £325. Not sure I’d be so keen to pay £600 for it.
Great tent though, it’s withstood plenty of wind and rain without missing a beat.
Hey up its Belper Bloke here, we have a Berghause Air 4, its the best tent we have ever had, great for two of us. check out other posts on the Air 4 tent, its a bit of a challenge at first to get it in the bag, but work towards the open valves. very dry and stable in strong winds. consider how many will be using the tent, don't go to big, as the bag is massive, we have a landrover and only just get all our kit in it.
go for it, Millets best place and try to get a deal.
