4100BCNW B'Alaska Bag Tail Trunk

Designed for simplicity and versatility, the 4100 can fit a wide variety of both motorcyles and ATVs thanks to universal fit cinch straps with traditional loop mount ends and a collapsible design. The easy to use cinch straps curve around the entire top from the bottom of the bag allowing for a firm fit and finish even when jam-packed to the brim. Without the use of internal stiffeners, this bag is exceptionally roomy when open, and easy to stash when not in use. Commonly used for motorcycle tail trunk or front / rear ATV rack storage.
