Using this rain parka is easy. Just zip it up using the 2 - way zipper before you head out on your bike. Adjust the three - piece hood for better visibility and the sleeve tops for a comfortable fit. When it comes to maintenance, it's recommended to wash it with mild detergent in a gentle cycle. Avoid using harsh chemicals or bleach as they may damage the fabric and the DWR coating. After washing, let it air dry. Store it in the provided storage bag when not in use. Keep in mind that although it's waterproof, don't expose it to extreme weather conditions for long periods. Also, check the reflection regularly to ensure it's still working well for your safety in the dark.
