This handy little waterproof storage case features two separate compartments. The top section is for your mobile with a clear cover so you can operate your phone without taking it out. There is a waterproof rubber port for feeding through your headphones so you can listen to your music or speak on your phone while riding. The bottom section is the perfect size for holding sunglasses, wallets, keys and knick-knacks. The case straps onto your bike frame so can be positioned for optimum viewing and operation and can be quickly released for taking with you when parked.
