Proof sweat-wicking undies are equipped with unique moisture-wicking lining designed to fight odors to help keep you fresh and confident.
If you want to refresh and sanitize your undies, simply add a few drops of vinegar or tea tree oil to your washing machine during the rinse cycle and complete washing as normal.
Will Proof leakproof undies feel fresh and dry?
Yes! Proof leakproof undies are designed with several layers of moisture-wicking, absorbent materials that pull moisture away from the body and into a super absorbent core. Our unique Leak-Loc® edges lock in liquid, keeping you leak-free, while antimicrobial fibers inhibit the growth of bacteria and fight odor to help you feel fresh.
Can I wear sweat wicking undies on my period?
Multitasking is what Proof was made for! Our wide range of absorbencies doesn’t just handle sweat, but can back up or replace pantyliners, pads, tampons, and cups. For a pair that will pull double duty for sweat and periods, select a pair based on your average flow. Win-win!
Are Proof leakproof undies washable?
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.
Are Proof sweat wicking undies breathable?
We keep things easy breezy - our undies are breathable and soft for an ultra-comfy feeling. Our breathable material allows air to penetrate the fabric, keeping you cool. Even our leak-protective core features lightweight, breathable fabric that absorbs moisture without feeling damp or clammy!
What pair of Proof sweat wicking undies is best for workouts?
Proof undies are great for working out - whether you’re doing sun salutations or breaking a serious sweat. Our underwear features non-restrictive stretch fabric that moves with your body, along with a discreet, leak-protective core that pulls in moisture and wicks sweat away from the body. For an invisible look even under your favorite leggings, we recommend The Thong or The Brief.
