Leak Protective Undies by Proof
Life comes with a whole lotta leaks - but the leaks and uncomfortable wetness after sex is no longer something you have to worry about. Proof leak proof underwear look and feel like normal undies and feature an absorbent core to lock in leaks to help keep you comfortable and dry.
Experiencing leaks after sex isn’t so glamorous - but it is totally normal and natural. During sex, your body secretes liquid that helps - ahem - lubricate down there. And if you’re doing the deed without a condom, you’ll experience even more leaking after sex. Many doctors and experts recommend using the restroom and showering to reduce leaking and maintain proper hygiene after intercourse.
You may be surprised to learn that many women experience leaking after sex for up to a day after intercourse - which can lead to some serious soggy sheets and uncomfortable undies!
That’s why we created a special collection of undies, designed to handle after sex leaks. Proof undies pull moisture away from the body, and keep leaks in the super absorbent core - not on your sheets!
Proof undies look and feel like your favorite normal undies and feature built-in protection for worry-free nights and mornings.
We typically suggest buying your normal size in undies, but if you’re unsure, check out our sizing guide to find your perfect fit!
Washing Proof leakproof underwear is easy! Proof undies feature strong protection, but should be washed gently. Simply toss in the washing machine on a delicate cycle, using cold water and mild detergents. Hang or lay flat to dry. No washing machine? Hand washing in cold water with a gentle detergent works great, too!
More helpful tips to care for your pair:
-Don’t wring or twist your undies - be gentle when washing Proof
-Hot water, harsh detergents, and bleach can damage the absorbent technology in Proof undies, so be sure to use cold water and mild detergent
-Hang or lay flat to dry - do not put in the dryer
-Proof undies have a super absorbent core that can take between 6 and 24 hours to dry. Heavier absorbency pairs have more layers of absorbent material, and will take longer to dry than our light pairs. To expedite the drying process, blot away excess moisture from the gusset before laying flat or hanging to dry.
-Want a refresh? To make your period undies fresh and remove any lingering odor, use a few drops of vinegar or tea tree oil during the rinse cycle of your wash - voila! So fresh and so clean.
Our collection of underwear for after sex leaks looks and feels like normal underwear, but has built-in protection to handle after sex leaks. Our unique multi-layer lining pulls moisture away from the body and into an absorbent core, allowing you to sleep easy or go about your day without worrying about excess wetness.
We’re not experts, but we’d like to think that not fighting over sleeping on the wet spot in bed increases relationship satisfaction (like, a lot). Thank us later.

Your hip and waist measurements are the most important size when finding the perfect fit.
Measure around your body as shown.
Find your waist measure by leaning over to one side. Where your body naturally creases is your where you will place the tape. Measure parallel to the ground.
For your hip measurement, turn to the side and locate the fullest part of your booty. Place the tape around your body, parallel to the floor, around the widest and fullest part of your hips and tush.
If your measurements fall into different size categories, your hip measurement will be most accurate.
