AltRider Hemisphere Tank Bag

The Hemisphere Tank Bag was designed by riders who were frustrated with luggage that fails in the field — zippers that jam, seams that leak, bags that fall apart on real rides. This bag solves those problems.

The deliberate shape works across motorcycle types. It clears vent hoses on dirt bikes, keeps the ignition accessible on larger bikes, and stays out of the way of controls. All harness buckles are sleeved under the bag, so nothing interferes with your legs whether you're sitting or standing.

The interior map pocket zips from the inside. That keeps moisture out — a detail most tank bags miss. The marine-grade vinyl face is UV-resistant and easy to see through. A small exterior pocket handles items you need without opening the main compartment.

Removable dividers let you organize the main compartment the way you want it. The waterproof liner can stay open for quick access or be sealed with the roll-top closure when the weather turns. Hard plastic stiffeners with closed-cell padding keep your gear stable and protected.

The Hemisphere Tank Bag is part of a full luggage system. It pairs with the Hemisphere Soft Panniers and Hemisphere Saddlebag for riders who want a complete setup.
