Used it for the first time today. Loved it. Backpack straps can be tucked into the shorter sissy bar sleeve so they don’t flop around. The larger sissy bar sleeve and the strap at the top that goes around the top of the sissy bar ensured my bag didn’t go anywhere. No more putting on and taking off my other sissy bar bag retainer straps. No more excess straps flapping in the wind…and no more sissy bar bag sliding side to side because I didn’t want to put on the retainer straps. Oh, and my old bag wasn’t waterproof. This Torque bag is a definite upgrade. Also, I got my purse and lunch kit in there with more than enough room to spare.
