The long zipper running almost around the entire perimeter of the pocket creates a large opening that allows comfortable handling of even larger items, while the pendant on the zipper runner greatly facilitates frequent opening and closing. The second zipper located in the lower part allows you to significantly increase the volume of the pocket if you need to carry a larger load. The attachment of the pocket to the saddle and seat post is ensured by the click system and velcro tape, which enable quick assembly and disassembly of the pocket. The reflective tape on the sides and back increases visibility in low-light conditions not only from the back, but also from the sides. The pocket is made of durable and tough Polyester 600D, which ensures a long life even with frequent use.
