One-Handed Jacket Zipper: Make Any Jacket One-Handed in 10 Minutes
October 12, 2026 · 5 min read
Short answer: the fastest way to get a one-handed jacket zipper is to add a magnetic zipper to the jacket you already own. ZipperBuddy zips onto your jacket's existing zipper in about 10 minutes, with no sewing, and puts a MagZip® in the middle. The magnets line up the bottom of the zipper for you, so you can close the jacket with one hand.
Zipping a jacket is two jobs. The second one is easy. The first one is not.
The real problem is the bottom of the zipper
Every separating zipper starts the same way. You hold the left half steady. You feed the pin on the right half down into the box at the bottom. You seat it all the way in, keep both halves level, and only then pull the slider up.
That first step takes two steady hands and both eyes. If one hand is busy, shaky, stiff, or missing, it does not happen. If the person wearing the jacket is four years old, it does not happen either. The rest of the zipper is fine. The bottom two inches are the whole problem.
Most of the advice online is about the pull tab. The pull tab was never the hard part.
Four ways people cope today
People are resourceful. Here is what actually gets tried, and what each one costs you.
1. Zipper pulls and rings
Good: cheap, easy to add, and they make the slider easier to grip.
Bad: they solve the pull, not the join. You still have to seat the pin in the box with two hands first.
2. Leave it zipped and pull it over your head
Good: costs nothing.
Bad: a zipped jacket has a small neck hole. It is slow, catches on glasses and hair, and only works on loose jackets.
3. Hook-and-loop conversions
Good: one-handed once it is done.
Bad: it is a permanent change, it can cost more than the jacket, it wears out and fills with lint, it does not block wind, and it looks like a Velcro jacket.
4. Buy a new easy-dressing coat
Good: it works out of the box.
Bad: the range is small, prices start well over $100, and your favorite jacket still hangs in the closet.
None of these are wrong. They are just workarounds for a two-inch problem at the bottom of the zipper.
A one-handed jacket zipper with ZipperBuddy
ZipperBuddy is two narrow strips of softshell fabric. Each strip has a #5 zipper half along its outside edge and a MagZip half along its inside edge. The outside edges zip onto your jacket's existing zipper, one strip per side. The inside edges are the new closure.
MagZip is a patented magnetic zipper base. Bring the two halves near each other and they pull together and line themselves up. You do not seat anything. You do not look down. You pull the slider up with one hand and the jacket is closed. MagZip launched with Under Armour and has been on major brands since, including Tommy Hilfiger and Lululemon.
ZipperBuddy takes that base and puts it in the middle of the jacket you already own.
How it installs
No sewing. No tools. No glue. About 10 minutes, once.
- Open the jacket all the way and lay it flat.
- Take the strip marked for the slider side of your jacket. Feed the top of its outer zipper half into your jacket's slider and zip the strip down onto that side.
- Take the other strip. Its outer zipper half has its own slider. Feed the other side of your jacket's zipper into it and zip that strip on.
- Close the middle. The two MagZip halves snap together and the center slider runs up. Check that the jacket hangs square.
Steps 2 and 3 are a two-hands job. Do it once with a helper if you need one. That is where the name comes from. After that, the jacket's original zipper stays zipped to the strips. The MagZip in the middle does the closing from then on. There is a full walkthrough on the install page.
How to measure
ZipperBuddy comes in 22, 24, 27, and 30 inch lengths, left or right slider side, and four colors. Custom lengths are available.
- Measure the zipper. Lay the jacket flat and zip it. Measure from the bottom stop to the top of the zipper, along the teeth. Choose the length at or just under that number. Most people land on 22 or 24.
- Note the slider side. Put the jacket on and look down. The half the slider rests on when the jacket is open is your side. Check on the body, not on the hanger.
- Pick the color. Black, white, gray, or blue. Choose the one that disappears into your jacket.
If you order the wrong length, we swap it.
Who it is for
- Kids learning to zip. The join is the part they cannot do yet. Take it away and they can dress themselves. The same base is built into our MagZip Kids Hoodie.
- One busy hand. A cast, a coffee, a baby on one arm, or a permanent situation. A jacket should not require two.
- Stiff fingers. When pinching a small pin into a small box is the hard part, removing that step helps.
- Caregivers dressing someone else. Magnets close it in one motion, even on a person who is moving.
What it does not do
ZipperBuddy fits separating zippers only: any jacket, coat, vest, or hoodie that opens all the way down the front. It does not fit pullovers, quarter-zips, pockets, or bags.
It fits #5 plastic-tooth zippers, because the strips zip onto your jacket's own zipper. Flip the slider over and look for a "5" stamped on the back, and confirm the teeth are molded plastic. Most fleece, softshell, and casual jackets pass. Many dress coats do not. Message us a photo of the slider if you are unsure.
Quick questions
Do I need to sew anything?
No. ZipperBuddy zips on. No needle, no tools.
Will my jacket look different?
Only up close. From a few feet away it looks like the same jacket.
Can I move it to another jacket?
Yes, if the other jacket has a #5 plastic-tooth separating zipper of a similar length.
