PUL Waterproof Barrier!
A thin waterproof layer is built right into every pair! It seals the liquid away the moment it happens, so it never reaches your skin or your clothes!
Holds 10 oz / 300 ml!
Each pair soaks up to 10 oz of liquid all by itself, with no extra pads needed! Perfect for light to moderate leaks all day long!
Dries Fast, No Smell!
It pulls wetness off your skin and dries quickly! That stops the build-up that causes odor, rashes, and itching!
Wear Them Again and Again!
Just toss them in the wash like normal underwear! Most men save over $100 a month by ditching disposable pads! Comes in sizes M to 6XL!
Three Smart Layers!
A soft inside layer pulls wetness off your skin, a thick middle layer soaks it up, and the waterproof outer layer locks it in! All inside a slim pair that looks just like normal boxer briefs!
Sealed Right Away!
The liquid gets sealed the second it's soaked up, so it never spreads to your clothes and never sits long enough to smell!
No One Can Tell!
No bulk, no diaper look, and no crinkle when you move! They stay hidden under jeans, shorts, slacks, or scrubs!
Just measure around your waist and pick the closest size below! Every pair has about 2 inches of stretch in the waistband, so if you're stuck between two sizes, size down for a snug fit or up for more room!

Questions? We've Got Answers.
Everything you need to know about Undwell before you order.
How do Undwell briefs work?
They use three smart layers! A soft inside layer pulls wetness off your skin, a thick middle layer soaks it up, and a waterproof outer layer locks it in. All inside a slim pair that looks just like normal boxer briefs!
How much can they hold?
Each pair soaks up to 10 oz (300 ml) of liquid all by itself, with no extra pads needed! That's enough to keep you covered through a full day of light to moderate leaks!
Are they really leakproof?
Yes! The waterproof barrier seals the liquid in the moment it's soaked up, so it never reaches your pants. For heavier leaks, just add a thin liner and the barrier still catches anything it misses!
Will anyone be able to tell I'm wearing them?
Not a chance! There's no bulk, no diaper look, and no crinkle when you move. They stay completely hidden under jeans, shorts, slacks, or scrubs!
Will they smell?
No! The waterproof layer seals the liquid away and dries fast, so it never sits long enough to build up odor. You stay fresh from morning to night!
Will they feel wet against my skin?
Nope! The soft inside layer pulls wetness away from your skin and into the core, so the part that touches you stays dry and comfortable all day!
Can I wear them overnight?
Yes! They're made to keep you dry and comfy all night so you can finally sleep without worrying about leaks. For heavier nights, add a thin liner for extra peace of mind!
How do I wash them?
It's easy! Give them a quick cold rinse, then machine wash cold on a gentle cycle with mild soap. Hang or lay flat to dry and they're ready to go again. Just skip the bleach, dryer, iron, and fabric softener!
How long do they last?
A long time! They're built to be washed and worn again and again, holding their protection wash after wash. Most men save over $100 a month by switching from disposable pads!
What size should I get?
Just go by your waist! Measure around your natural waistline and pick the closest size. We carry M all the way up to 6XL, so there's a perfect fit for everyone!
What if I'm between sizes?
Every pair has about 2 inches of stretch in the waistband! If you're stuck between two sizes, size down for a snug fit or size up for a little extra room!
How long does shipping take?
Every USA order ships free and arrives in 7 to 14 business days! You'll get a tracking number as soon as your order is on the way!
Is the packaging discreet?
Always! Your order ships in a plain, unmarked box. Nothing on the outside shows what's inside, so your privacy is fully protected!
What's your return policy?
You're covered by our 90-day money-back guarantee! Wear them, wash them, and try them for a full 90 days. If you don't love them, we'll swap them, give you store credit, or refund you in full!
