Repairing and maintaining your hiking gear will extend its lifespan, which is great both for your wallet and the planet. A busted zipper is no reason to trash your favorite jacket (or sleeping bag or pack). With a few tools, you can fix a broken zipper that separates or broken slider at home or in the backcountry.
The most common reason for a broken zipper is separation—when you zip the slider to the top, but the teeth don’t engage, leaving you exposed to chill or with your tent fly flapping in the wind. This type of failure is caused by a loose slider that’s unable to push the zipper coils together.
When you’re back home, consider replacing the zipper slider for a more long-term fix.
A multitool can get you out of a bind if your zipper malfunctions in the backcountry.
Zippers have a thankless job, despite offering a critical function. Rarely do they receive much attention unless they actually break—which they tend to do at the worst possible time. Zippers most often fail for two basic reasons: overuse and underuse.
Overuse often results in the aforementioned separated zipper. Over time, the tension on the slider loosens to the point it can no longer apply enough pressure to pull the teeth together. Overuse can also result in a bent zipper track, especially if you’ve forced the zipper up while it was biting a piece of fabric. A visual inspection will reveal bent or broken teeth. At that point, it’s time to bring in your gear to a shop for a repair. If you’re in the backcountry, you may have to turn to old reliable duct tape as a temporary fix.
Underuse damage can occur when your gear is stored for an extended amount of time without maintenance. Gear-Aid makes zipper cleaner and lubrication oil which is perfect for when you are initially storing your gear or when it emerges from dormancy. It’s also a good part of routine gear maintenance. Checking in on your zipper health at least once a year is a good idea across all your gear—backpacks, tents, jackets, first-aid kits, and anything else that relies on zippers.
It’s worth noting that most zippers tend to fail slowly, over a series of weeks or months. Zippers tend to be highly reliable and can withstand a lot of abuse. That’s pretty impressive for a device that hasn’t changed much since its initial invention in 1851. If your zippers start snagging or causing gaps in sections of teeth, give them a tune-up. A little bit of preventative maintenance can save you time and money by avoiding a trip to your local gear shop (tailors and alteration stores can often repair zippers as well).
While tightening your zipper’s slider is a good stopgap solution, you’ll likely want to replace the slider for a more longterm fix. Luckily, fixing a split zipper—the kind used on sleeping bags and jackets—is dead easy. You’ll need a zipper repair kit from a company like GearAid, a wire cutter, and a pair of needle-nose pliers. Start by using your wire cutters to snip off the top stop on your zipper and removing the slider. Put on a new slider of the same size, running it down from the top where you clipped off the stop. Finally, use your pliers to crimp on a replacement zipper stop.
