This SB360 sissy bar roll bag is made of sturdy water resistant nylon and
measures 18 inches wide by 9 inches tall. It has a removable carry handle and
two removable quick release straps for extra mounting stability, or to tie
additional items to the outside of the bag. Mounting this bag is really simple.
Just slide your backrest through these hook and loop straps and pull them
tight... There are two zippered pockets on the sides of the roll bag and the
zippered main closure opens up wide for easy access. The SB360 also comes with a
complementary rain cover as well, although it requires a little modification
before it can be used. The opening of the cover is on the side which doesn't
allow the cover to be installed with the bag mounted. I found an easy fix for
this issue. I simply cut four small slits in the cover to accommodate the exit
of the mounting straps and install the waterproof cover before mounting the bag
to the bike. I also used packaging tape to seal the seams of the cover to ensure
that no water can get in...
