Rhinowalk Motorcycle Tail Bag — Expandable 23L-35L Waterproof Helmet Bag, Matt Black with Hard-Shell Top

The Rhinowalk Motorcycle Tail Bag is an expandable, hard-shell 23L–35L waterproof travel bag designed to carry a full-face helmet and protect gear in all-weather riding.

This compact but roomy tail bag combines a rigid ABS-style top shell with a waterproof inner liner and taped seams so your helmet, clothes, and camera kit stay dry and secure on long rides. Built to fasten directly to a passenger seat, rack, or sissy bar with 360° rotating buckles and four-point straps, the bag also converts to a backpack via included shoulder straps for easy off-bike transport.

How much can the bag hold and will it fit my helmet?

The bag expands from a contracted 23 liters to a full 35 liters, giving flexible capacity for different trips. When fully expanded, it comfortably accommodates a full-face helmet plus clothes or smaller gear thanks to dedicated internal space.

• Contracted size: 23L for compact travel or commuter use
• Expanded size: 35L to accept a full-face helmet and extra items
• Dimensions: approx. 16.14 x 14.17 x 10.24 in (top), 14.96 in (expanded)
• Separate compartments and internal space for camera or clothing

Will it stand up to rain, splashes, and rough roads?

Yes — the bag pairs an enforced polyester waterproof inner bag (PU6000MM rating) with thermal-welded seam tape to resist water ingress. The integrated molded top shell adds impact protection for bumps and travel wear.

• Waterproof inner bag with PU6000MM fabric
• Seams sealed by heat-welded rubber tape
• ABS-style hard top shell for abrasion and drop resistance
• Designed for all-weather commuting and touring

How does it attach to my bike and can I carry it off the motorcycle?

Installation uses four buckle straps and 360° rotatable UFO buckles to secure the bag to passenger seats, sissy bars, or luggage racks without a dedicated rack. Two hook-and-loop shoulder straps attach via D-rings to convert the tail bag into a backpack for walking around or daily errands.

• Four-point strap system for stable mounting without a rack
• 360° rotating buckles help align straps for neat installation
• Includes two shoulder straps to convert to a wearable backpack
• Hook buckles and D-rings supplied for quick changes between carry modes

What accessories and materials are included and how durable is it?

The package includes shoulder straps, four fixing straps, and a waterproof inner bag, all built from heavy-duty materials for long service life. The upgraded ABS-style top and reinforced fabrics resist abrasion and compression during normal touring and storage.

• Included accessories: 2 shoulder straps, 4 buckle fixing straps, 1 waterproof inner bag
• Top cover: integrated compression-molded ABS-style hard shell
• Exterior fabric: reinforced polyester with sealed seams
• Hardware: robust UFO buckles and D-ring connections
