Frequently Asked Questions
Are these helmets waterproof?
Helmets are not waterproof products; they provide splash and visor protection for the rider's face and keep padding dry in light rain. For sustained downpours, pair a helmet with a rain jacket or waterproof helmet cover.
Will the KEMIMOTO bag keep electronics dry?
The KEMIMOTO rack bag uses water-resistant PVC and a sealed zipper that protects items during routine commutes and short showers, but its seams are not fully welded — avoid prolonged exposure or submersion and consider an inner dry sack for electronics.
How do I stop a rack bag from sliding in wet conditions?
Choose a bag with multiple attachment points and wide Velcro or buckle straps; ensure straps are tightened to the rack and tuck excess material to prevent movement. Some riders add non-slip padding or a secondary strap around the rack for extra security.
