More info
Our most absorbent women's underwear is ideal for nighttime.

Holds up to 6 cups with reinforced side leak guards
Soft, breathable material is comfortable all day and night.

Premium Overnight Plus is our most absorbent underwear, designed for ultimate nighttime comfort and protection.

This incontinence underwear for women absorbs 37% more than leading brands. Constructed with a dual absorption core and reinforced side guards, it holds up to 6 cups of liquid and prevents leaks, even when you're lying down. These heavy absorbency incontinence briefs are designed specifically for a woman's body to ensure optimal comfort and fit. Moisture is quickly wicked away from the body and odors are locked in to keep you feeling fresh and dry all night long.

The cloth-like material with breathable panels is soft against the skin, while added spandex creates a more form-fitting silhouette. This adult pull up is latex-free and has tear-away side seams for quick and easy removal. Available in white.

For added protection, use with Because Boosters for an extra 4 cups of absorption.

We're excited to announce that this collection is sustainably produced in the US in a carbon neutral facility with post-consumer recycled packaging.

Pieces per Pack:
S/M: 20 pieces per pack
L: 20 pieces per pack

XXL: 10 pieces per pack
How to use
Use in place of regular underwear to absorb urine leaks. Slip on, with black square indicator as the back of the underwear. Slip off or tear sides for easy disposal.

For added discretion, use with Because Disposal Bags to dispose.

Alexi, Because co-founder, with his mom

Why we started

Alexi started Because for his grandmother — his Nonna — after countless trips to local stores turned up nothing that actually worked. Luca started it for a father who had quietly stopped going out. They made what their own family needed, then made it for everyone else’s. It now arrives at over a million doors.

— Alexi & Luca, co‑founders

Questions, answered

How does the subscription work?

Pick a size and delivery frequency, and we ship automatically at 10% off every order with free shipping. You can pause, skip, swap, or cancel anytime from your account — no phone calls required.

How is Sensitive different from Overnight Plus?

The Sensitive line is designed for sensitive skin: a 100% plant-based topsheet spun from sugarcane gives a super-soft feel, and it’s free from fragrances, parabens, chlorine, PFAS, and latex. Both absorb up to 6 cups.

How do I choose the right size?

Measure your waist and hips and check our size chart. A good fit is snug but not tight — 50% of leaks are caused by incorrect fit, so it’s worth a minute to check.

Can I use FSA/HSA funds?

Yes — all our bladder protection products are FSA/HSA eligible, so you can pay with pre-tax dollars.

Is the packaging really discreet?

Completely. Orders arrive in plain, unmarked packaging with nothing on the outside that indicates what’s inside.
