Back bands

Some kayaks come with woefully inadequately supported back bands, but no worries, they can easily be fixed with the addition of or merely changing to a firmer--usually larger bungy cords for the fine adjustments.
The back band is not there as a back rest, but that doesn't mean it is just a useless decoration. You do need firm support in your lower back, so any modifications should be done with that goal in mind.
