Top FAQs
see all FAQSAre Proof leak protective undies good for pregnancy?
Yes!
We’ve curated a collection for pregnancy with non-restrictive, low-rise silhouettes to accommodate a growing bump and leak-protective core to keep you dry and protected without added bulk. The absorbent core helps with any little leak that accompanies pregnancy - whether it’s discharge, sweat, or a little bladder leak from when baby kicks your bladder (it happens to us all!).
What is the best style of underwear for pregnancy?
Pregnancy comes with a lot of changes - a growing bump, extra sweat, and even unexpected leaks. We designed a collection of underwear specifically for pregnancy to keep you comfortable and dry for the whole nine months (and beyond!).
The best underwear for pregnancy have a non-restrictive, low-rise silhouette which accommodates for a growing bump and widening hips. Breathable stretch fabric is super important, as well, to move with your body as it changes. Last but not least, we designed our collection of maternity underwear with added protection for your peace of mind. Proof maternity underwear feature a range of built-in leak-protective linings that pull moisture away from the body - whether it’s sweat, discharge, or light bladder leaks that accompany pregnancy.
What size should I order in Proof maternity undies?
Our maternity collection features multi-way stretch fabric and non-restrictive waist bands to accommodate for that beautiful bump! Most mamas find they are comfortable in their typical size - but when in doubt, check out our size guide for a perfect fit.
Are Proof leakproof undies washable?
Washing Proof maternity 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.
What makes Proof maternity undies different from regular underwear?
Our undies fit and feel just like regular panties, but feature a super absorbent core to keep you protected from leaks and a non-restrictive waistband and buttery soft stretch fabric to keep you feeling oh-so-comfy for the whole nine months of pregnancy.
Are Proof maternity undies seamless?
Our maternity underwear are designed to provide discreet protection without added bulk. Some of our undies are designed with seamless edges, while others have smooth, bonded edges. For an invisible look under clothing (maternity leggings included!) we recommend The Everyday Undie, The Thong, or The Brief.
Can I wear The Thong while pregnant?
Definitely! The Thong by Proof is perfect for pregnancy, as the low rise silhouette and non-restrictive stretch fabric moves with a growing bump. Added protection is excellent for all of those little leaks that come along with pregnancy, and keep you protected without added bulk. For an excellent fit during pregnancy, you may want to size up one size.
