"If you are looking for a heavy-duty car cover that can stand up to the harshest sunbaked environment, then check out the Covercraft WeatherShield HD Car Cover! It is constructed from a heavier denier thread for maximum UV opacity that is developed primarily for intense sun environments and long-term storage. Approximately 40% heavier than WeatherShield HP, the 300 denier fiber construction results in almost double the tear and tensile strength, finished with the same great EPIC® by Nextec encapsulation process. Covercraft partnered with Nextec Applications, inc., a technology leader that pioneered a new process for creating performance fabrics used primarily in the outdoor clothing industry. Through precise polymer placement and special chemistries, they were able to place protective finishes inside the fabric, encapsulating the actual woven fibers to transform ordinary fabric into extra-ordinary! Covercraft created what is considered the ""Perfect"" fabric for outdoor or indoor vehicle protection. | Covercraft WeatherShield HD Car Cover C10133HG"
