Small articles can just slide right into the top of the Framepack, but for larger items, you may need to loosen the front strap for a little extra room.
Load your stuff
Drop all of your things into the open-top of the Framepack.
Tighten the front strap
Give the front strap a tug to tighten everything up. You might have to hold the other side of the strap to prevent the Framepack from rotating.
All set!
Double check that all buckles are secure and the straps are tucked in, then you are good to ride.
