Why do I suddenly find my zipper down all the time?

Half witted like me. Same problem on some days.

This has happened to me about a six or seven times in the past month with a couple of different pair of jeans. I feel like a man checking my fly constantly. I hadn’t thought about the fabric softener. I thought my menopausal hormones were acting up again.

Zippers have a little tab on them kind of like a tiny pin, when the zipper is pulled up and then dropped it flops down and the little pin stops it from coming undone. If this little pin is broken or missing your zipper will constantly fall down.

It’s not that your zipper is down. Hell, that’s probably been the case forever. Most likely you are getting to be an old fart and are aware of any little draft. Now, instead of flying open you’re closing up shop early so you don’t catch cold.

This has happened to me several times and I am not even half your age. My Dad told me something similar to what @poisonedantidote told you. I bought dress pants recently and it feels good to not have a zipper on those! They are so comfortable, too. Maybe you could try wearing different pants (that don’t have zippers) if this keeps happening to you.

I hate to have to introduce you to the Four Stages of Aging. You’re really not going to like the next one.

Stage 1 – You forget names. Well, we all do that, right?

Stage 2 – You forget faces. Admit it. You’ve been here, too, haven’t you?

Stage 3 – You forget to zip up ‘after’. The answer to your immediate question.

Stage 4 – You forget to unzip ‘before’. I told you that you wouldn’t like it.

Either old “thickie” has figured out how to get out of the cage, and has been trolling, or you are simply forgetting to close the barn door. Either way, you might want to double check when leaving the bathroom.
By the way, that checking the zipper motion outside of the bathroom is how aliens identify each other. I learned that from Bart Simpson.

Is it the same pair of pants all the time? Is it the same brand of pants all the time?

If the problem is a falling zipper (and not that you just forget to zip up), you could try sticking a rubber band through the hole on the zipper pull and hooking the ends around the button.

P.S.: Chrome tells me that “zipper” is misspelled.

You are going to have to move in to jogging pants or elastic belt pants. Stay away from playgrounds.

My husband was at the bank and the young female teller had he zipper down. He told me when he got home that he didn’t tell her. Poor girl!

^^ He was probably worried she’d be thinking “Why are you looking there?”

Maybe the zippers are wearing out? Time to go shopping.

It is gravity.
All things drop when you are aging, zippers included.
