Buying Guide

Match capacity to helmet size

Choose luggage with sufficient liters or expandability — 35–48L top cases or expandable tail bags that list 7–14L ensure room for full-face and modular helmets

Prefer hard cases for secure storage

Hard-shell top cases (e.g., 35L–48L models) provide better impact protection and lockability than soft bags for commuting and touring

Look for expandability for flexible use

Expandable tail bags let you compress for solo rides or expand when carrying a helmet or extra gear, improving value and versatility

Check waterproofing and covers

Waterproof materials and included rain covers help protect helmet interiors from moisture; many tail bags advertise waterproof covers as a feature

Consider mounting and compatibility

Verify that tail bags secure to rear seats or racks and that top cases fit your bike or scooter mounting plate to avoid fitment issues
