They are all double wall , between 4 and 5 lbs.
Be careful with the budget tents, often the weight is under-stated and some don't stand up to much wind or rain.
Single wall tents that work, like the Tarptents/SMD/Black Diamond are over $250.
The Double Rainbow will keep you dry and stand up to reasonable wind gusts, is half of the weight of the above but $260.
