Buckles:
Be careful with buckles, as stepping on them, getting them caught on or trapped in things, such as a car boot, can lead to invisible weak points. If you are using your rucksack for a prolonged period of time, take replacement buckles with you that can be attached to the straps without the need for sewing.
Tears:
You can seal any tears in the pack sacks by using fabric tape.
You can use a pair of pliers to lightly pinch the slider so that the zip fastens again reliably.
