The Delta Pocket attaches around the sling of the Billingham '5 series' and '7 series' bags.
This includes the following: 225/335/445/555/107/207/307/307L
To attach to a compatible bag, simply unclip the leather straps on the sides of the pocket and wrap them round either side of the sling, where the sling is split into two. Secure using the press studs.
