HeyBeautie LeakProof Panties FAQs
Our Leakproof Underwear features triple layer technology that ensures you stay fresh, dry, and protected. The anti-odor top layer wicks away moisture from your skin; the inner-layer absorbs the liquid and locks it in; and the leak resistant outer layer keeps any liquid from spotting your clothes.
Our Leakproof Period Underwear feature barely-there built-in panty liners that can absorb between 1 and 8 tampons worth of liquid, providing you with confident protection against period leaks, light bladder leaks, and sweat.
Our Essential Underwear feature a moisture-wicking breathable gusset that keeps sweat and odor away, but they do not provide any leakproof protection.
Depending on the level of absorbency of leakproof period underwear you choose and the heaviness of your flow, you can wear our period panties on their own or as backup protection along with a menstrual cup or tampon. You're totally protected with our high and super absorbency leakproof underwear, while our low and medium absorbency leakproof underwear can replace pads and tampons on lighter days and work great as a backup for your usual period protection on heavier days.
Yes! Our underwear are the perfect protection against LBL. In fact, it was the frustrations and unnecessary stress of postpartum leaking that inspired our CEO Joanna to make her first pair of Knix. If you're one of the 1-in-4 women who experience light bladder leaks, our incontinence underwear are here for you. They absorb up to 8 tsp of liquid and feature a moisture-wicking, anti-odor, and bacteriostatic properties to keep you feeling fresh, dry, and confident.
Washing your leakproof underwear shouldn't be complicated, so we designed our products to be super easy to wash and care for. For best results, machine wash on cold with mild detergent, and either tumble dry on low (Super Leakproof Underwear) or lay flat to dry (all other Leakproof products). That's it! Pro tips: Don't use softener or bleach and never iron.
Our Leakproof Underwear use natural moisture-wicking and anti-microbial materials in the gusset liner. They help prevent yeast infections by moving moisture away from your skin and inhibiting the growth of bacteria.
