Introducing the "UV Protection Cover" designed for outdoor use with mechanical traps and drainage traps. If dirt adheres to it, you can easily keep it clean by wiping it with a cloth dampened with water. Additionally, since intermediate-type water vests (transparent products) deteriorate more quickly due to UV exposure, we recommend installing the "UV Protection Cover" for outdoor use. 【Features】 ■ Made of nylon tarpaulin, making it resistant to water and dirt ■ If dirt adheres, it can be kept clean by simply wiping it with a cloth dampened with water ■ The joints use Velcro, allowing for easy installation by simply wrapping it around the main body ■ Custom orders for colored versions are available (standard product is gray) *For more details, please download the PDF or feel free to contact us.
