5 Surprisingly Useful Things You Can Make from an Unused Underx Brief

diy diapers hacks

Momentum Digital |

Because when life gives you extra briefs… you get creative.

We don’t recommend wearing them on your head, but if you’ve ever found an unused Underx brief that’s the wrong size or style—don’t toss it. These things are engineered for absorption, comfort, and containment. Which, it turns out, makes them perfect for more than one kind of mess.

1. The Plant Pot Liner

Use it when: your houseplants are leaking more than your coffee schedule allows.

How: Cut the brief open along the side seams and lay the absorbent layer flat inside a planter before adding soil. It works like a water reservoir—keeping the dirt moist longer and preventing leaks from the bottom. Bonus: no soggy windowsills.

Why it works: The same material that keeps you dry helps keep roots hydrated. Circle of life, just cleaner.

2. The Emergency Spill Absorber

Use it when: your pet, your kid, or your late-night drink makes a surprise appearance on the floor.

How: Cut out the core padding (the part that does the magic) and press it firmly on the spill. It’ll soak up liquids faster than paper towels and won’t shred apart in the process. Dispose when done, or marvel at your ingenuity first.

Pro tip: Keep one in your car or cleaning caddy. It’s the unsung hero of “oh no” moments.

3. The Ice Pack Wrap

Use it when: you need a cold compress that doesn’t drip or slide off mid-soothe.

How: Slip an ice pack (or a few cubes in a sealed bag) into the brief’s main compartment. The absorbent core holds condensation and provides cushioning, while the elastic edges keep everything snug. Great for knees, ankles, or egos after slipping on said spill from #2.

Optional: Use painter’s tape or a reusable band to keep it in place—no leaks, no cold shocks, no problem.

4. The Pet Water-Bowl Mat

Use it when: your dog drinks like he’s auditioning for a waterpark.

How: Place an unused brief under your pet’s food and water bowls, inner padding facing up. It catches drips, splashes, and the occasional “enthusiastic” shake-off. When it’s time to replace, just roll it up and toss it—no mildew mats, no funky smell.

Bonus: Great for under litter boxes or muddy paw rinse stations, too.

5. The Road-Trip Trash Bag

Use it when: you’re traveling, snacking, and generating more mini-trash than you expected.

How: Open the waistband slightly and set it in your car’s side compartment or door pocket. The snug elastic holds wrappers in, and the odor-controlling core keeps it fresher than your fast-food stop. Empty and replace when full.

Yes, really: it’s leak-proof. You’ll thank yourself later.

Bonus Hack: The Drawer Freshener

Use it when: your laundry drawer smells a little too “lived in.”

How: Sprinkle a few tablespoons of baking soda into an unused brief, tie it off with a rubber band, and tuck it in your drawer. It works like a scent sachet—odor control, Underx-style.

Bottom line: comfort and containment are a lifestyle. Even when you’re not wearing them.
