• Quality Hardware Zipper: Frosted, textured zipper head with durable metal hardware — smooth to open, reliable to close, and built to last ride after ride.
• Non-Slip Woven Texture: Distinctive weave finish increases surface friction for a secure, wear-resistant exterior that also looks great on the road.
• Adjustable Buckle Strap: Stable, shake-free mounting system with an adjustable nylon Velcro strap (laid flat: 16.5 cm) that fits most standard bicycle seat posts.
