Q. Can I wear your underwear when I have my period?
Yup -- that’s what we’re here for. Our Fresh Fix Technology acts like a barely-there built-in panty liner that can absorb as much liquid as two regular tampons, and you can find it in most of our underwear silhouettes. It is a magical and all-natural moisture-wicking, leak-proof, absorbent, and anti-odor material, so you’ll stay dry and comfortable (it has saved the day on more than one occasion). It will feel slightly different than your regular underwear — because it is! — but most women find they forget they're wearing it. We recommend our Fresh Fix products for backup protection during a heavy flow, on its own at the end of your cycle, or for breakthrough bleeding.
It’s also perfect for women who experience light bladder leaks, wear panty liners on a regular basis, or are concerned about excess sweating. Just wear, wash, and repeat, and you’ll have one less thing to worry about.
Want to give it a try? Make sure to choose underwear marked "Leak Proof" while shopping on our website.
Q. I experience light bladder leaks. Is your product for me?
Yes! In fact, the frustrations and unnecessary stress of postpartum leaking is what inspired our CEO Joanna to make her first pair of Knixwear. If you are one of the 1-in-4 women who experience light bladder leaks, our leak-proof products are here for you. They absorb up to 3 tsp of liquid and feature a moisture-wicking, anti-odor, and antimicrobial cotton top layer to keep you feeling fresh, dry, and confident.
Q. Can I wear my Knixwear during a workout?
We love a good sweat. All Knixwear products use our innovative performance fabric that wicks away sweat and naturally destroys odor. The quick-dry material keeps you cool and calm, no matter the heat. In fact, many of our most loyal customers are outdoor enthusiasts: one backpacker told us our bras and undies are the only ones she’ll travel with, since they stay smelling fresh for so much longer! (Bonus: the seamless fit is totally invisible under workout leggings :) )
Q. How do I care for my Knixwear?
We’re not into fussy, so all Knixwear intimates are designed to be machine washable. Wash in cold water with mild detergent and lay flat to dry. Avoid fabric softener or bleach. For best results, toss them in a lingerie bag or wash with similar items.
For our Leak-Proof line of underwear, give them a quick rinse before tossing them in the wash.
Q. Is your seamless underwear truly seamless?
Yes! We make incredible seamless underwear. Both our basic Knix and athletic lines are seamless and feature bonded technology (that means no bulky stitching) to ensure our seams lie flat and stay in place — no bunching, pinching, or rolling. In fact, our underwear is so seamless that it has become a staple in the equestrian community — it’s invisible even under those super tight, white riding pants.
Q. What’s the difference between the Everyday underwear and the Athletic underwear line?
All of our underwear shares the same seamless look, innovative bonded construction, and amazing comfort.
Our Athletic underwear is made of high performing LYCRA FreshFX® fabric that wicks away moisture and sweat for your most fast and furious workouts. It also features LYCRA® Sport technology to maximize freedom of movement, compression, stretch, and recovery. The stretch tech means these will relax a bit more than the Everyday line.
Our original seamless Everyday underwear is made of our patented lightweight fabric that is designed to feel light as air — naked, but better — and features our soft velvet flocking around the waist and leg holes. You’ll find the same moisture-wicking and odor-killing properties as in our Athletic line, but these are concentrated in the gusset. Our Everyday underwear keep their shape beautifully, and will hug you more snugly than our Athletic line.
Q. How long will my Knixwear last?
We designed our fabrics with an Italian garmentory and built our technology into the actual fiber. That means no chemicals next to your important bits, and our performance features will never wash out. We’ve found that our products are up to 5x more durable than regular underwear — so you can expect to be wearing your Knixwear for years to come.
Q. What’s my size?
Our sizing might be a bit different than what you’re used to. We wear-tested our bras and underwear on hundreds of women of all different shapes and sizes, and worked with a universal fit model to get our fit just right. Please refer to our sizing chart to find your perfect size.

Q. My bra feels tight. Is that normal?
Our bras were designed to mold to your unique shape. For that reason, you’ll probably notice that the fit will be tight when you first put it on. Our innovative fabrics actually stretch to support your body. Basically, it means you’re wearing the bra — the bra isn’t wearing you! We recommend giving it 30 days to see how the fit of the bra evolves. Most women are amazed by how perfect the fit becomes!
If you still aren’t happy after 30 days, we’ll help you find your right size — or take the bra back, no questions asked.
Q. I have a larger bust. Will your bra support me?
Over 70% of our bra sales are to women with cup size D or larger. Why? Well, despite the fact that the average bra size in the U.S. is 34D, traditional retailers simply don’t cater to most women. When we set out to make our Evolution Bra, we knew we wanted to accommodate the widest range of sizes and shapes we could, and to make every woman feel confident, comfortable, and supported by her bra. That’s why our Evolution Bra is available up to size 42E, with more sizes on the way.
Q. What is your return/exchange policy?
We want you to love your Knixwear as much as we do!
Our bras are designed to mold to your unique shape, which is why we’ve got our 30 day wash-and-wear guarantee. Wear your bra to yoga, while running errands, or even to sleep in. Then, toss it in the washing machine and start again. If after 30 days you’re still not happy with the fit, let us know and we’ll initiate an exchange or return.
In the event of an exchange, you’ll receive an e-giftcard for the value of the original purchase that you can redeem against a new size. Credit for an eligible return will be refunded back to your original form of payment within approximately 7-10 days.
