My new Raincover Essential for the Urban Arrow Family seems used.

When the Rain Cover Essential comes out of the packaging there can be some cracks and white powder on the transparant parts. The white is powder to prevent the material sticks to each other. The cracks will disappear during use. You can clean it up by using a damp microfiber cloth, you can swipe of the powder very easily. If you're not satisfied with the product, you can return it at the shop you bought it from. Maybe the Rain Cover Plus is more to your liking?
