This is one of the best ideas for the 2008 season - the Atrium is essentially a sun canopy for small tents which will create a great sheltered dining/cooking/sitting area on those balmy summer evenings (Barmy in Stan's case). The Atrium is designed to fit onto the front pole of any tunnel tent or dome tent (with a porch pole). The height of the Atrium can be adjusted to suit but the ballpark height for a good fit is 1.3-1.5m. The construction is 9.5mm Fibreglass poles with 185T Polyester flysheet (5000mm HH).
