MOSISO Motorcycle Tail Bag 10L Waterproof Saddle Bag — Black, Convertible Shoulder Carry

MOSISO's waterproof motorcycle tail bag is a compact 10L saddle pack built to keep essentials dry, secure, and easy to grab on and off your bike.

This durable, weather-resistant tail bag converts quickly between a rear-mounted motorcycle bag, a shoulder bag, or a handheld carry—making it a flexible storage solution for daily commutes and weekend rides. Sized at 12.6 x 10.24 x 7.09 inches, the bag balances low-profile carriage with a roomy main compartment for phone, wallet, cables, power bank, a small bottle, and basic tools. Thoughtful attachment hardware and a grippy base help the pack stay put during bumpy roads while a top handle and adjustable strap let you carry it off the bike without extra gear.

How much gear can fit into this MOSISO tail bag?

The main compartment holds about 10 liters—roomy for daily essentials without becoming bulky on the rear seat. Internal layout is simple for quick access while the exterior is compact enough to preserve rider posture and visibility.

• 10L main compartment suitable for phone, wallet, cables, power bank, small bottle, and tools
• External silhouette: 12.6 x 10.24 x 7.09 inches for most motorcycle seats
• Lightweight structure keeps total added weight low for handling stability

Will this bag stand up to rain, mud, and street grime?

The outer layer uses waterproof PU leather to shield contents from rain and road spray. Seams and fastenings are designed to limit quick ingress of water and grit, though prolonged submersion should be avoided.

• Waterproof PU leather exterior repels rain and mud
• Quick-clean surface wipes down after wet rides
• Zipper placement and flap design reduce direct exposure to spray

How does the bag attach to the motorcycle and stay stable?

Four buckles plus two rear seat straps secure the bag to a variety of tail shapes and luggage plates. An anti-slip bottom and low center of mass reduce sliding and shifting during acceleration or on rough pavement.

• Four-buckle system with two backseat straps for firm mounting
• Anti-slip bottom surface prevents unwanted movement on rugged roads
• Compact profile minimizes wind resistance and keeps weight close to seat

Can I carry this off the bike comfortably?

Yes—the pack converts to shoulder or hand carry with a detachable, adjustable strap and a cushioned top handle. Strap length adjusts from roughly 28.35 to 50.39 inches so you can sling it across your body or shorten it as a shoulder bag.

• Detachable shoulder strap adjusts between 28.35" and 50.39" for different carry styles
• Top handle provides quick grab-and-go convenience
• Use as motorcycle tail bag, shoulder bag, or handheld tote

Who is this for: Riders who want a minimalist, weather-resistant storage solution that stays secure on most motorcycle rear seats and doubles as everyday carry off the bike. It’s a good fit for commuters, errand riders, or weekend motorcyclists who need organized, easy-access space for essentials without bulky panniers.
