Navy This is a waterproof cover suitable for medium to large backpacks. My child used it twice and then stored it away. It comes with a cover and is compact, so you can quickly take it out in sudden rain, providing peace of mind. It was purchased as a school-specified item, so it is very durable. It can be used for a wide range of activities, such as commuting to school or work, and mountain climbing. Instant purchase OK! I will ship it immediately! #Compatible with 18-55L #Essential for sudden rain #Rainy day must-have #Backpack cover #Waterproof #Rainy season measures #Reflector reflection #With tape #Easy to attach #Disaster preparedness
