New etiquette for rainy days: a lightweight, breathable, and water-resistant umbrella cover with high strength. When you put a wet umbrella inside, it won't get your clothes or bag wet, even if they're touching. You won't bother others, even in a crowd. It uses a high-strength material with excellent breathability and water resistance. It can be used for both long umbrellas and folding umbrellas. It folds up small and is convenient to carry. With a natural, calming design, it's easy to match with any outfit.
