Wear and Tear: Polyester bike covers are designed to protect your bike from external elements like rain, sun, dust, and dirt. Over time, these covers will naturally experience wear and tear due to exposure to the environment, which is not typically covered under a warranty.
Material Durability: While polyester is durable and water-resistant, it's still prone to fading, tearing, or becoming worn down after prolonged use. These types of issues are usually considered part of the natural lifecycle of a product and not covered by a warranty.
