I have 3 containers I put in this sissy bar bag: I put in 1 container a battery jumper, a tire inflator, and a giant portable charger- I keep this stuff at the bottom of the sissy bar bag. The second container is my school backpack that holds my laptop, textbook, notebook, and gym clothes- I keep this in the middle of the torque bag. The 3rd container is a big First Aid kit with 4 tourniquets, chest seals, wraps, etc(all the good stuff) and I keep this at the top of the torque bag. I have also attached a wide horizontal pouch to the molle on the bag that has a wrench, sockets and a few extra bolts I have lost in the past.
This Torque bag holds all of that has been on my bike at freeway speeds a bunch of times and I haven't had any issues, this bag has been great!
