A somewhat unusual feature of the Bontrager Adventure is that it can only be filled from one side. This is fine when the handlebar bag is fully loaded, otherwise there is a risk of imbalance during distribution. Good: When packing, a valve allows air to escape. There is an elasticated drawstring at the front for clothing...
