MOSISO Motorcycle Tail Bag 10L Waterproof Saddle Bag, Black — Convertible Shoulder Strap & Anti-Slip Base

MOSISO's Motorcycle Tail Bag is a 10L waterproof polyester saddle bag that secures to your bike and converts to a shoulder bag for off-bike use.

Whether commuting, touring, or running errands, this compact MOSISO tail bag offers weather-resistant storage, multiple carry options, and a stable mounting system designed to fit most motorcycles. Built from PU-coated polyester with an anti-slip base and four buckles plus rear straps, it protects essentials like electronics, tools, and snacks while keeping them within easy reach.

How much can this saddle bag hold during a ride?

The main compartment provides roughly 10 liters of space, sized to carry daily essentials without overhanging the seat. Its interior fits items such as a phone, wallet, small power bank, cables, and a compact repair kit, keeping weight centered and balanced on the rear seat.

• Dimensions: 12.6 x 10.24 x 7.09 inches (L x W x H).
• 10L main compartment for carry-on items.

Will it stay in place on rough roads and in wet weather?

The bag mounts securely using two backseat straps plus four buckles that lock it to the bike, while an anti-slip bottom reduces lateral movement over uneven surfaces. The PU-coated polyester exterior sheds rain and road spray to help keep contents dry in light to moderate conditions.

• Four-buckle securing system and two rear straps for firm attachment.
• Anti-slip bottom design to minimize sliding on bumpy rides.
• Waterproof PU leather coating resists rain, mud, and dust.

How can I carry the bag off the bike?

MOSISO designed this tail bag to convert quickly into a shoulder bag or handheld tote. A removable, adjustable shoulder strap and a top carry handle let you transition from riding to walking without transferring contents to another bag.

• Adjustable shoulder strap ranges from 28.35 to 50.39 inches.
• Top handle for easy hand-carrying when dismounted.
• Converts between tail bag, shoulder bag, and handbag configurations.

What construction and convenience features are included?

The bag uses durable polyester reinforced with a waterproof PU finish for everyday abrasion resistance and easier cleaning. Thoughtful touches—like the zippered main compartment, reinforced buckles, and compact footprint—make packing, attaching, and accessing gear simpler while riding.

• Durable waterproof PU leather material for surface protection.
• Zippered main compartment for secure storage.
• Compact footprint that fits most motorcycle rear seats without obstructing passenger space.

Who is this for? Riders who need a versatile, weather-resistant tail bag for daily commuting, weekend touring, or quick errands will find MOSISO's 10L saddle bag useful. It suits solo commuters, scooter and motorcycle owners who prefer compact storage that converts to a shoulder bag, and anyone wanting an easy-to-mount bag that protects electronics and small essentials from road grime and light rain.
