The Eurovent Montreux is definitely a Four Season awning. The roof and walls are made from heavy duty PVC, and the stitching protected by a sealed waterproof cover. The steel frame features seven roof poles and two cross poles that maintain the structure of the frame in the event of strong winds, heavy rainfall or snow. The Montreux prices include an additional inner roof lining to reduce condensation and regulate the temperature inside the awning. When you are out, you can close all windows with their zipped shutters. On warm days, the Montreux can be turned into a sun canopy thanks to its removable front and side walls.
