        I was worried people might notice, but honestly, it looks and feels just like my regular underwear. No one can tell, and I feel safe all day.

        Martin

      • Game changer!

        After years of using pads, I can’t believe the difference. No more shifting or discomfort — just one pair of underwear that does it all.

        Patrick

      • So comfortable.

        I was skeptical at first, but the fit is perfect. Soft, breathable, and I forget I’m even wearing leak-proof underwear.

        Daniel

      • Boosted my confidence.

        Alain

      • Works better than expected.

        I’ve tried other brands and they all felt bulky or plasticky. Underzip feels natural, and it truly keeps me protected.

        Marc

      • Finally a solution.

        After my surgery, I struggled with small leaks. Underzip was the first thing that actually made me feel secure again.

      • Worth every penny.

        Not only do they work, but I’m saving money by not buying disposable pads anymore. Plus, they’re better for the environment.

        Eric

      • Stylish and practical.

        Honestly, I thought they’d look medical but they don’t. They look like my normal boxers, and that makes me feel much more confident.

        FAQ

        Why did you choose the name Underzip?

        We wanted a name that felt fresh, modern, and confident — without being tied directly to “incontinence” or “medical” terms. Too often, brands in this space sound clinical, when what people really need is something that blends into everyday life.

        Underzip was born from that idea: it’s sleek, easy to say, and instantly reminds you of something close to you — your underwear. It’s not about zippers, it’s about confidence you can zip back into your life.

        For us, the name represents freedom, discretion, and strength — values that go far beyond a product. It’s about helping people feel like themselves again, without compromise.

        Do I have to pay for shipping?

        We offer free shipping on all orders above 50$. For smaller orders, a standard shipping fee applies and is shown at checkout.

        How can I get in touch with you?

        You can reach us anytime through our contact page or by email at contact@underzip.com Our team will respond within 24 hours.

        How does the leak-proof technology in the underwear work?

        Each pair has a discreet multi-layer system: a breathable outer fabric, a soft inner lining for comfort, and an absorbent, waterproof core that locks in leaks while keeping you dry.

        How do I wash the underwear?

        Underzip underwear is fully washable. Simply machine wash cold and hang dry — no special care needed. Avoid fabric softeners and bleach to keep the technology effective.

        What size do I need?

        Check our size guide before ordering. If you’re between sizes, we recommend choosing the larger one for comfort.

        What if the underwear doesn’t fit?

        No worries — we offer easy exchanges. Just contact us within 30 days, and we’ll guide you through the process.

        Which payment methods can I use?

        We accept major credit and debit cards and other secure payment options shown at checkout.

        How can I track my order?

        As soon as your order ships, you’ll receive a tracking link via email so you can follow your delivery in real time.

        How long will it take to receive my order?

        Orders are typically delivered within 7–11 business days, depending on your location.

        What are the return conditions?

        You can return unused, unwashed items in their original packaging within 30 days of delivery.
