Coverking has comprised Triguard out of three layers and each layer is treated with UV retardant for protection against the sun's rays and radiation. The middle layer of polypropylene goes through a meltblown procedure which means that it is heated and rolled so that it is water-resistant. 

The middle layer is then inserted between two layers of Spunbound fabric which means it is compressed in a way to allow breathability in return preventing mildew and rot build up.

 Triguard's lightweight material is also easy to clean and store.
