To find out more about the Fuse-on system: http://www.fusion-bags.com/collections/fuse-on-bags
If a Fusion bag displays a rubber "Fuse-on" badge it indicates that it can be attached quickly and easily onto the front of an instrument bag with four strong hook-and-loop straps that are fed through D rings. Most instrument bags can only hold one attachment bag but the Guitar bag can hold two, one on the headstock and one on the base of the instrument. This concept has been developed especially for musicians who are travelling or lead busy lifestyles and need extra space to carry accessories, food & drinks, spare clothing or even a laptop.
