You're packing for a trip, pull the zip round and it jams. Or worse — the teeth split open behind the slider and the case gapes. A broken zip is one of the most common luggage problems we see, and it tends to happen at the worst moment.
It rarely means the case is finished. Often only the slider needs replacing, which is a small job. Here's why zips fail, how to get through a trip on a broken one, and when to bring it in.
Why luggage zips fail
- Overpacking. A very common cause. When a case is stuffed past its capacity, the zip is what's holding it shut. Over time — or all at once — the teeth part or the slider gives out.
- Wear. A slider wears a little on every pass. After years of travel it can loosen enough that it no longer pulls the teeth together.
- Light, cheap parts. Thin zips and soft sliders on budget luggage bend, corrode and split sooner.
- Snagged fabric. Lining or clothing caught in the teeth can force the slider off track or bend individual teeth.
- Rough handling. Bags get dropped, stacked and squeezed. A hard knock to the zip area can crack the slider or knock the teeth out of line.
Getting through the trip
Flight in three hours and no time for a repair? These get a case home. None of them is a fix.
Pull snapped off? Use a paperclip
If only the pull tab has broken and the slider still works, thread a paperclip or a key ring through the hole in the slider. That gives you enough grip until it's repaired.
Teeth split? Pin them
Close the gap with safety pins through the fabric on either side, at short intervals. It's not pretty, but it keeps your things in.
Sticking? Use a pencil
Rub a graphite pencil along the teeth. The graphite works as a dry lubricant and often frees a zip that's catching.
Won't close at all? Strap or wrap it
A luggage strap, or a few layers of stretch film, will hold a case shut through the hold.
When it needs a repair
Bring it in when:
- Teeth are bent, broken or missing — no amount of working the slider will fix that
- The slider is cracked or loose and no longer pulls the teeth together
- The tape (the fabric strip the teeth sit on) is torn or fraying
- Your temporary fix keeps failing
- It's the main compartment — you don't want that opening in the hold
What happens at the bench
- We check what's actually failed. A lot of "broken zips" only need a new slider. That's quicker and cheaper than replacing the whole zip, and we'll tell you if that's all it needs.
- If the zip itself has to go, we unpick the original stitching without damaging the lining or shell.
- We match the replacement to the gauge, length and type of the original, so the slider, the pulls and your lock still line up.
- We stitch the new zip in so it sits flat and runs smoothly with the case fully packed.
- We test it — open, close and under load — before it goes back to you.
A new zip may look slightly different from the original, especially on an older case. We'll tell you before we start if we can't get a close match.
Does the zip brand matter?
Yes, somewhat. You'll often see "YKK" stamped on a slider — they're one of the largest zip makers and widely used on luggage. What matters more than the name is the gauge (how heavy the teeth are) and the slider: a heavier, well-finished zip holds up noticeably better than a thin one on a case that gets checked in.
If you're having a zip replaced anywhere, ask what's going in and whether it matches the original's size.
What it costs
It depends on what's needed:
- Slider only or full zip — a new slider is the smaller job
- Where it is — a main-compartment zip is longer and more work than a pocket zip
- The case — hard-shell cases need more care to remove and refit than soft-sided bags
Current zip and slider prices, with usual turnaround, are on our repair services page. For a good-quality case, it's usually well below the price of a new one. The quote is free, and we give it before any work starts.
Keeping the new zip healthy
- Don't overpack. If you have to force the zip shut, the case is too full.
- Close zips fully before check-in. A half-open zip is easy to snag.
- Keep the teeth clean. Wipe them with a damp cloth after dusty or beach trips.
- Lubricate now and then with zip wax or a graphite pencil.
- Pull along the track, not at an angle. Yanking sideways strains the teeth and bends the slider.
- Keep lining and straps clear of the teeth as you close it.
