Thinx for All Leaks are machine-washable, reusable underwear designed to replace single-use disposables. They come in discreet designs that look and feel like regular underwear. Just wear, wash, and reuse them again and again. They absorb leaks, control odors, and wick away moisture — so you can stay fresh and dry no matter what.
Our underwear is built with 4 ultra-thin layers of leak-absorbing fabric, located in the center panel of the underwear. It wicks away moisture, controls odor, and leaves you feeling fresh and dry.
We've got you covered! Our underwear's ultra-thin tech found in the gusset of the underwear controls odors — so you don't have to worry about anything other than staying fresh & dry.
Thinx for All Leaks absorbs bladder leaks, up to 6 tablespoons. They feature 3 layers of ultra-thin absorbent technology built into the gusset: an innermost layer of moisture-wicking cotton, a super absorbent inner lining, and an outermost layer that acts as a leak-resistant barrier.
They sure are! Thinx for All Leaks is machine-washable and reusable, so you can wear, wash, and wear again, just like regular underwear. Leaks shouldn't disrupt your lifestyle — you can finally ditch inconvenient and uncomfortable pantyliners for good.
Our gusset is made up of multiple absorbent layers found in the center panel of the underwear. It sits under the front of the vulva with leak protection that extends throughout the back of the underwear — making it ideal coverage for light to moderate bladder leaks.
Thinx for All Leaks wicks away moisture, sweat, and leaks (so yes, our underwear may be your new workout buddy.)
We've found that the majority of our folks require light to moderate protection. We designed our underwear to absorb up to 100 mL worth of leaks. For some people, that means all day protection. That being said, we don't recommend using our product for a full bladder release.
Our underwear's ultra-thin, built-in tech is designed to absorb without feeling bulky. Our moisture-wicking barrier helps prevent wetness, so you stay fresh and dry. If you feel wet, it's most likely a sign that it's time for a fresh pair.
Nope! Thinx for All Leaks is a sustainable alternative to pantyliners and other disposables. Every pair features built-in absorbent tech for comfortable, discreet protection. You can finally say goodbye to last-minute trips to the drug store and digging through your bag for a spare liner.

Thinx for All Leaks is machine-washable and reusable. Wear, wash, and wear again, just as you would regular underwear. Machine wash on cold with the rest of your laundry. Be sure to avoid using bleach, fabric softener, or high heat from dryers or irons. Tumble dry low or hang dry. Check out our How to Wash page for more information and helpful tips!
Yes, you can wash them with your other clothes without issue. If it makes you more comfortable, you can also give them a quick rinse after use, allow them to dry, then throw them in the hamper for laundry day.
Machine wash cold — this will help keep your underwear in tip-top shape!
We discourage using fabric softener because it breaks down the fabrics in the center panel of the underwear and the bonding around the seams, which helps absorb and keep leaks in. Over time, fabric softener will make the underwear less absorbent.
Our absorbent underwear isn’t stain-proof, although the materials used in our absorbent gusset are largely stain-resistant. Thinx Inc. absorbent underwear is also lined in black to prevent stains from showing. To further prevent stains, follow the washing instructions on our How to Wash page.
Hang drying times may vary depending on where you hang them up, but our styles typically dry within 19 hours.
Don’t worry — a few instances of high heat isn't a big deal. However, repeated exposure to high temperatures can change the fit of the underwear or cause shrinkage, so do your best not to make a habit of it!
If the recommended care instructions are followed, Thinx for All Leaks should not be prone to shrinking. Consistently using high heat, such as machine drying on high or ironing may cause the underwear to shrink. To avoid this, try your best to always tumble dry low or hang dry after washing.
Thinx Inc. absorbent underwear will last at maximum tech performance for the industry standard of about 40 washes or approximately 2 years (or longer!) when cared for properly. Check out our How to Wash page for more information.
We know that some of our fibers do not decompose quickly into the soil — however, we’re proud to say that you *can* recycle our period underwear! Here’s how to do it:

We aim to create underwear that champions and supports bodies throughout different stages of life. From your first period to post-menopause and all the leaks in between. We aim to empower our customers with sustainable solutions while breaking taboos around bladder leaks and menstruation.
We craft our underwear carefully and consciously, from sustainable manufacturing processes to ethical working conditions. We’re proud to work with MAS, a global leader in ethical manufacturing based in Sri Lanka. MAS operates under three pillars: products changed for good, our planet changed for good, and lives changed for good. Visit our Manufacturing page to learn more about how we make our underwear and the incredible people who make them!
Since day one, giving back to our community has been at the core of our mission. We're committed to paying it forward through our giveback programs and initiatives. When you purchase Thinx products, you're supporting our mission to empower *every body* through advocating for sustainable, scalable solutions to ending period poverty — learn more about GiveRise. In addition, we're honored to team up with organizations doing incredible work as our quarterly cart donation partners. Past partners have included The Trevor Project, the Black Mamas Matter Alliance, the Chicago Period Project, and others.
You aren't required to send the undies back to us for your return, we encourage you to pass them along to a friend or donate them to a local women's shelter! You can find a great guide on shelter facilities closest to you here.

Thinx for All Leaks Signature styles are the same Speax silhouettes you know and love, just with a different name. Our Thinx for All Leaks Essential styles are brand new — offered in a streamlined collection of silhouettes and colors for less.
We recently rebranded from Speax to Thinx for All Leaks, so some items may still have the previous labels and tags. Don't worry — the products shown on our website are the same products you will receive!
While the 3-layer tech that makes these products absorbent is similar, the specific makeup and composition of the layers differ between Thinx and Thinx for All Leaks to account for the differences in pH and viscosity between period flow and bladder leaks.
We specifically designed Thinx for All Leaks to tackle the pH and viscosity of bladder leaks, which is lower than that of menstrual flow. If you experience light incontinence and your period, Thinx for All Leaks would be your best bet to prevent all your leaks. We don't recommend using our period underwear to protect against bladder leaks.
Thinx Inc. underwear is certified based on the rigorous chemical safety requirements of the STANDARD 100 by OEKO-TEX® [20.HUS.04850 | HOHENSTEIN HTTI]. We ensure that all materials from suppliers are OEKO-TEX® certified, too. We also test our finished products through an accredited, globally recognized third-party laboratory to ensure they are compliant with U.S. and international regulations.We conduct absorbency testing — which tests the absorbency capacity of each underwear style and wear tests — which evaluate the absorbency capacity of each underwear style when worn by actual people who experience periods and bladder leaks. Both tests are conducted in globally accredited laboratories to ensure our results align with industry standards. We use fit models to ensure our products sit just right!

We recently rebranded from Speax to Thinx for All Leaks, so some items may still have the previous labels and tags. Don't worry — the products shown on our website are the same products you will receive!

Bladder leaks are way more common than most people think! That's why we aim to empower our customers with sustainable solutions while breaking the taboo and stigma around bladder leaks.
There isn’t a one-size-fits-all answer to *why* leaks happen. Several life experiences, such as perimenopause and menopause, pregnancy and childbirth, and physical exertion, may increase your odds. Bladder leaks can also spring from having surgery that affects your pelvic floor muscles (ex. hysterectomy) or as an offshoot of an underlying health condition. Whatever the reason for your leak, Thinx for All Leaks is a sustainable solution to staying fresh and dry all day while still feeling like yourself!
The answer to why you’re leaking involves the state of your pelvic floor, in one way or another. There are a variety of healing techniques that can help overcome pelvic floor dysfunction, including breathing exercises such as yoga or meditation, pelvic floor exercises (think Kegels), pelvic floor physical therapy, mindful eating, and improving stress levels. To learn more, check out our blog, Foreword!

Our referral program is one way for you to spread the Thinx Inc. love! If you refer a friend, they get $10 to spend on any Thinx Inc. product (Thinx for All Leaks, Thinx, or Thinx Teens™). If they make a purchase, you also get $10 in credits. You can earn up to $500 in Thinx inc. credit by referring up to 50 friends. To get started, sign up or log in to your account. Share your unique referral link directly or through email, SMS, WhatsApp, or Facebook!
You can view your earned, pending, and redeemed credits by visiting the Referral Dashboard tab on your account page. If you are the referrer, your credits will be unlocked after one week — unless the person you referred to has canceled their order.
Yes — you can earn up to $500 in Thinx inc. credit by referring up to 50 friends. After that, your friends who are new customers will keep receiving $10 promo codes but you will not accrue any more credits on your account.
For every new customer, you refer, you will earn a $10 credit to apply toward any Thinx Inc. purchase (Thinx for All Leaks, Thinx, or Thinx Teens™). So, if you refer three new customers, you'll have $30 to spend. You can use your credits all at once or split your credits across orders until you use all credits.
With each referral, you earn ten credits, which is the equivalent of $10! One credit = $1.
No, credits are calculated in USD and not converted to other currencies due to limitations with our partner, FriendBuy. If you select your local currency from the currency dropdown, the prices onsite will be reflected in that currency, but your credits will be USD.
If you are the referrer, you can stack your referral credits with up to one discount code and use an unlimited amount of gift cards. If you are the referee, your code is not stackable with other promo codes.
You can only refer new customers.
No, you can refer as many people as you want, so refer away!

If you reside in one of these countries, you are unfortunately ineligible to refer or be referred by others. We're sorry about the inconvenience!
If you’re referring a friend, your $10 in credits are unlocked in one week (after they make a purchase) as long as the order isn't canceled. If you're a new customer referred by a friend, you can use your referral code immediately to get $10 off your first order of $35 or more.
Unfortunately, if your referral cancels their order, you won’t receive the $10 credit.
