It’s hassle-free, all-year protection. **Q: Are there different color options for the cover? Does color affect protection?** A: We mainly offer dark-colored covers, which provide better UV protection, stain resistance, and long-lasting good looks. Protection performance is not affected by color—all colors use the same multi-layer protective construction. **Q: What if the size doesn’t fit or there’s a quality issue?** A: We recommend sizing up rather than down. A slightly larger cover is easier to secure and offers better overall protection. If you have any material or quality issues, we’ll assist you promptly. **Q: How do I clean a dirty cover? Is machine washable?** A: For daily cleaning, wipe or rinse with water. For tough stains, gently scrub with mild detergent and air dry completely before storage.Machine washing is not recommended, as it may damage the waterproof coating.
