Car side awnings are often used by campers, and they essentially provide nice areas of shelter beside your car. They’re not usually large in size whilst they’re mounted to roof racks.
A car side waning will also be a really nice touch for a picnic if you don’t want the unpleasant weather to ruin your day, and these awnings can be put up in seconds, offering a good level of protection against rain, sun and wind.
Shapes and sizes do vary, though hexagonal design tend to be the most common, while the awning fabric tends to be made entirely out of Polyester, with the only other addition being support poles.
