Using the Blackburn Outpost Elite Hitchhiker Bag is a breeze. First, install it using the included [2] short bar straps and [2] long bar straps with G - hooks on your bike. You can use it on its own or pair it with other bar rolls. When packing, put small items like your phone in the internal pocket for easy access. For extra layers or items, use the outer bungee to lash them. To keep the bag in good condition, after use, wipe it down if it gets dirty. Make sure to dry it thoroughly if it gets wet to maintain its water - resistance. Also, don't overstuff the bag to avoid damaging the secure closure.
