BOOST is the long version of our top tube bag, ideal for use on gravel bikes as part of a larger bikepacking setup. It is also particularly suitable for MTB bikes with sloped frames, which reduce available space and limit the use of bikepacking bags.

The BOOST bag is waterproof, features a convenient double-zip closure, and an opening for a battery cable to charge electronic devices on the go. It is very practical as it has two external elastic mesh pockets, two adjustable internal dividers useful for organizing contents as you wish, and a reinforced, covered structural base to prevent scratching the items stored inside the bag.

It can be attached to the frame using the supplied strap fasteners, or it can be secured via the threaded top tube mounts common to many gravel bike models.
