Hey there, ladies! If you‘re on the hunt for premium intimates and activewear that are as comfortable as they are functional, you‘ll definitely want to get acquainted with Knix. This innovative Canadian brand has been shaking up the industry with their thoughtful, solution-oriented designs made for real women‘s bodies and lifestyles.
As your trusted fashionista friend, I‘ve put together the ultimate Knix review to give you the inside scoop on everything this size-inclusive brand has to offer. We‘ll dive into their bestselling bras, leak-proof underwear, and ultra-cozy loungewear so you can decide if Knix deserves a place in your top drawer. Let‘s get started!
What is Knix?
Founded in 2013 by Joanna Griffiths, Knix is a Toronto-based intimates company on a mission to empower women with products that make us feel more comfortable and confident in our own skin. They‘ve become best known for their patented leak-proof underwear, but Knix offers a full range of undergarments and apparel designed to address common pain points like chafing, lack of support, and ill-fitting bras.
One of the things I love most about Knix is their commitment to celebrating all women. They were one of the first major brands to completely ditch models and photoshop, instead featuring untouched photos of real customers of all ages, shapes, and sizes across their site and social media. With cups from A-G and bands from 28-44, Knix is serious about creating products for every body.
Knix Bras Review
On the hunt for the perfect bra? Knix has you covered with a wide array of sizes and super comfy styles for every occasion. Their bras are designed with busy, active lifestyles in mind, so you can count on meaningful features like wireless support, moisture-wicking fabrics, and no-slip straps.
The Knix Catalyst is their #1 sports bra, and for good reason. Tested against 800 other styles, this high-impact bra came out on top for its impressive bounce control and comfort. The V-shaped back allows for great range of motion and the molded cups provide separation and shaping, even without pesky wires.
For everyday wear, the "8-in-1" Evolution Bra is a fan favorite thanks to its ultra-soft, seamless construction and reversible design that gives you two bras in one. The lightweight, 4-way stretch fabric feels barely there but still delivers gentle support ideal for A-C cups. Plus, you can style it multiple ways, from classic to cross-back!
Rounding out Knix‘s bra collection are their maternity and nursing styles, which feature the same comfort-driven design with a healthy dose of new mom-friendly function. Their leakproof nursing bra is a postpartum game-changer, with absorbent cups that hold up to 2 oz of milk to protect you from embarrassing leaks.
Knix Underwear Review
Now, let‘s talk panties. If you‘re tired of underwear that rides up, digs in, or lets you down during that time of the month, Knix has your back (and your booty). All of their undies are made with super breathable, quick-drying fabrics and feature a gusset lining for added freshness. And just like their bras, Knix offers an inclusive size range from XS-XXXXL.
But Knix‘s real claim to fame is their leakproof line, designed to protect you from bladder leaks, periods, and pesky discharge. Using the same tech as their nursing bras, these revolutionary undies have a barely-there built-in lining that can hold up to 8 tsp of liquid (for reference, a regular tampon or pad maxes out at 5).
I‘m a big fan of their Leakproof Boyshorts for sleeping and lounging during my cycle, but they also come in thong, bikini, and high-waist cuts to suit every style and flow. The seamless design disappears under clothes while the absorbent gusset keeps you feeling dry and fresh.
If you‘re not in the market for period panties, Knix still has plenty to offer, from buttery-soft modal thongs to cotton bikinis. Their Thigh Saver shorts are an especially clever addition, perfect for preventing the dreaded inner-thigh chafe under dresses and skirts. The lightweight, stretchy fabric stays put without squeezing and the 5" inseam provides ample coverage.
Knix Apparel Review
Bras and undies aren‘t the only tricks up Knix‘s sleeve. In recent years, they‘ve expanded into comfy basics and activewear essentials that complement their original product line. Think: soft, wireless bralettes, supportive mesh leggings, and versatile tanks, all with the same thoughtful construction and size inclusivity we‘ve come to expect from Knix.
Their Papaya line puts a stylish twist on performance fabrics, with punchy prints and on-trend details like curvy seams and split hems. The Papaya Sculpt leggings use 4-way stretch compression to smooth and support, while flat-locked seams and a wide, high-rise waistband ensure a dig-free fit. Pair with the Papaya Bliss Tank for a tropical pop of color and breathable mesh panels that‘ll keep you cool through any workout.
For maximum chill, Knix‘s modal separates and pajama sets deliver with luxe, touchable fabrics you‘ll want to live in. Their All Day Lounge collection features a wire-free bra alternative with light support perfect for WFH life, plus a chic high-neck tank and wide-leg pants that feel cozy but look put-together (because you never know when that Zoom call will come in).
What Customers Are Saying
You don‘t have to take my word for it – the proof is in the community of passionate Knix fans who rave about these intimates. With over 19,000 reviews and an average 4.4-star rating on their site, it‘s clear that once people try Knix, they‘re hooked.
"Most comfortable bra I‘ve ever worn," one reviewer gushes about the Evolution bra. "It‘s supportive, looks great under clothes, and feels like I‘m wearing nothing. I have several and they‘ve held up really well over the past year of regular washing. Can‘t recommend enough!"
"Total game changer," another says of Knix‘s leakproof boyshorts. "I can wear these all day on my heavy days with no leaks. Way more comfortable than disposable pads and better for the environment. They stay in place, don‘t feel wet, and rinse clean so easily."
While the majority of feedback on Knix is overwhelmingly positive, no brand is without a few complaints. The most common callouts I found were around long shipping times (likely due to the huge demand!) and inconsistent sizing between different underwear styles. A few reviewers also felt that the absorbent gussets on the leakproof line were a bit too thick/noticeable for their taste.
Is Knix Worth It?
Now for the million dollar question: is Knix worth your hard-earned cash? IMHO, if you‘re fed up with pokey wires, saggy elastic, and uncomfy undergarments in general, Knix‘s innovative intimates are 100% worth a try.
Their thoughtful, technology-driven designs address so many of the pain points women face, from boob sweat to midnight tampon leaks. I‘m especially impressed by the way Knix combines this function-first engineering with the kind of soft, stretchy, feels-like-nothing‘s-there fabrics you actually want against your most sensitive areas.
Sure, they‘re a bit spendier than your average Hanes multipack, but with Knix, you‘re investing in high-quality pieces that are built to last. Compared to other period panty brands, like Thinx, or high-impact sports bras from the likes of Lululemon, Knix‘s prices are actually quite reasonable. They also offer bundles and multipacks so you can save on your faves.
I do wish they had a longer trial/return window than 30 days, but I appreciate that you can wear and wash your bras and undies before deciding if they‘re right for you. And if you‘re not totally satisfied, their customer service team is super friendly and responsive (speaking from experience).
The Final Verdict
That brings us to the end of this epic Knix review! If you‘re still on the fence, here‘s my take: if you‘re looking for underwear and intimates that truly work for your unique body and lifestyle, Knix is the brand to beat.
From bounce-free sports bras to VPL-proof thongs to period panties that put tampons to shame, every piece they make is designed to make your life comfier, easier, and leak-free. Rookie moms, fitness fiends, and every woman in between will find something to love at Knix – and probably end up replacing their whole intimates drawer in the process.
But the real win is in their inclusive, body-positive ethos and refreshing commitment to using real women across their site. In an industry where photoshop and unattainable models are still the norm, it‘s empowering to see yourself reflected in a brand. By celebrating beauty in all its forms and creating products that address our real-life needs, Knix isn‘t just making better underwear – they‘re redefining what a modern intimates brand should be.
So, boob sweat be darned, I‘m a Knix convert through and through. Take it from this bona fide bra snob: your boobs, butt, and bank account will thank you for giving this brilliant brand a spin.
