Heavy messenger bag it? That the tube package is definitely a good partner when you are cycling!
Design according to personal needs of different size, easy bikers carry cell phones, cameras, keys, coins bills, credit card insurance card, toilet paper ... etc.
Use non-slip material lining cloth, so that the tube package would not have been slid back and forth on the tube when you ride!
The outer layer chosen based on personal preferences of different materials, laminated waterproof canvas, if rain does not wet your stuff!
Inner and outer layers can be made according to individual needs to do one or two inside and outside the band, easy to carry items bikers!
Usually, when a tube pack can be directly used as a purse or clutch, go phone, camera, keys, coins, cards caught away,
Very convenient and there is a sense of design!
ps (all goods are a dust cover will be bundled)
