Check first for trapped fabric caught in the zip teeth — gently working the slider back and forth while pulling the fabric clear resolves the majority of jams without any tools. If the zip moves stiffly rather than catching on something visible, a small amount of graphite pencil lead or a dedicated zipper lubricant rubbed along the teeth usually restores smooth movement.
Avoid forcing a stuck zip, which can bend the slider or tear the fabric at the seam — both harder and more expensive to fix than the original jam.
What travelers ask
What if the zip pull itself has come off?
A missing pull tab can usually be replaced with a small loop of cord or a keyring threaded through the zip slider, restoring grip without needing to replace the whole zip mechanism — a genuinely broken slider is the point where professional repair or replacement becomes worthwhile.
