Tent canopies. If you need some extra space when you are camping, why not take a look at a tent canopy or tent extension. Tent canopies are a great way of gaining valuable living space, providing a rain shelter for cooking, or a sun shade for the kids. Tent extensions make a great storage area for bikes and other bits of equipment for your holiday. We sell tent canopies and extensions from a number of manufacturers, including Coleman and Vango.
