Examine the bag exterior for surface cracks, wear patches, or brittleness
ContextHold the bag under a strong light and flex it gently in your hands. Leather bags develop micro-cracks at fold points over time, particularly near the drone stocks and chanter stock where the hide undergoes the most stress. A crack you can feel with your thumbnail may not be leaking yet, but it marks a countdown to failure. Synthetic bags (Gore-Tex, imitation leather, Bannatyne hide) rarely crack but can develop delamination at seam lines — run your fingers deliberately along every seam. A crack longer than 5mm on a leather bag means plan for bag replacement within two to three months; patching is temporary and rarely holds under sustained playing pressure.
