Knix Underwear Reviews

Knix designs underwear for everyone; you’ll find designs in high rise, bikini, shorts, cheeky, and thongs. Underwear is created to be seamless, smooth, and invisible, so you’ll feel comfortable all day long.

What Absorbency Levels Does Knix Offer?

You can choose from four different absorbency levels:

  • Super Absorbent underwear absorbs approximately eight tsp of liquid, equivalent to 8 regular tampons worth. They are a total replacement for disposal period products.
  • High Absorbent underwear absorbs slightly less, absorbing four to six tsp of liquid.
  • Medium Absorbent underwear is an excellent backup to your usual period product, meaning you can stay confident throughout your heaviest days. This type of Knix period underwear absorbs up to three tsp.
  • Then, we have the light absorbent underwear, which protects you on your lighter days.

You might be wondering how you will wash the Knix period underwear; well, Knix has made that easy too; you need to put them in your machine on a cold cycle with mild detergent and then tumble on low heat.

It can be pretty daunting changing from your regular period product to period underwear. Knix period underwear has been designed to be entirely relied on; you do not need a backup, ensure you have purchased the right absorbency level for your menstrual flow.

Period Underwear

For those of you, who are fed up with expensive, uncomfortable disposal pads or tampons, Knix period underwear could work for you. Knix period underwear is made with three layers, which ensure you are protected throughout your entire cycle.

  • The first layer is an anti-odor top layer; this layer removes moisture from your skin.
  • The second layer, the inner layer, absorbs all the liquid and locks it away.
  • Finally, there is a leak-resistant layer on the outside of the underwear; this layer protects your clothes from spotting.

With one in four women suffering from leakage during their monthly cycle, Knixwear underwear is a great all-month-long underwear.  

Knixwear Super Leakproof Boyshorts

The Super leakproof boyshorts are the most absorbent period underwear ever, absorbing the equivalent of eight tampons of blood each time you wear them. You can discard disposable products in favor of these extremely comfortable and machine-washable boy short underwear with a super absorbency rating.

Knixwear’s Super Leakproof boyshorts cost $30 and come in seven standard colors as well as several limited-edition colors.

The boyshorts are a popular choice among Knix customers, earning 4.7 stars from 615 reviews.

Customers have expressed how comfortable the super absorbent boy shorts are, how absorbent they are, and how confident they will not leak during their period.

There were a few negative reviews; customers complained about the pad section being too far forward and being too heavy.

Knixwear Leakproof Bikini Underwear

The Leakproof bikini is machine-washable, comfortable bikini underwear that features Knix’s patented leakproof technology, which absorbs up to 3 teaspoons of liquid; blood, pee, or sweat.

The classic mid-rise silhouette offers moderate coverage through the hips and bum and features an ultra-thin and absorbent gusset that measures approximately 7.5 to 8.5 inches in length.

This medium-absorbent bikini underwear provides confident coverage in the front and back. It can be worn alone on light days or as a secondary layer of protection on those heavier days.

Perfect as backup protection on heavier days of your cycle, on its own on lighter days, or assisting you in dealing with light bladder leaks.

Customers adore the leakproof bikinis, with over 2,650 reviews averaging 4.6 stars.

Customers appreciate that you can wear them with confidence and that they are so comfortable that they forget they are wearing them.

I love these underwear so much! They have literally changed my life to make my period much less stressful – almost to the point that I forget I’m in my cycle! I don’t stress about leaks ever!!

Five-star review @Knix.

Wish I could give these 5 stars, I loved them for the first few wears. At that time would have highly recommended! Unfortunately, after about 2 or 3 wears and following the wash instructions, they stretched out a ton. I followed the sizing chart and ordered size small. They are so saggy and barely wearable now. Definitely disappointed based on the price point. Still recommend the product overall, but caution on them stretching out.

One-star review @Knix.

KT By Knix Review

If you are shopping for someone younger, KT by Knix offers cute, comfy, and period-proof underwear for teenagers.

These underwear kits differ from the regular Knix brand in that they are specifically designed for smaller, growing bodies.

KT period underwear is available in junior sizes with smaller leg openings.

Knix Teen Period Underwear Kit

This period kit for teenagers includes two pairs of black teen super leakproof underwear that absorb up to 8 teaspoons of blood or the equivalent of eight tampons.

It also contains two limited edition color teen leakproof underwear for light to medium days and as backup protection for disposables, which absorb up to three tampons of blood.

The comfy and protective black sleepover short absorbs up to four tampons of blood. The kit also comes with a handy reusable pouch to store all of their period necessities, all for the price of $99.

The teen period kit provides 100% period-proof protection for the duration of a teenager’s cycle, eliminating the need for disposables and accidental leakage.

To date, the period kit has received two five-star reviews.

According to both reviews, teenagers love period kits because they alleviate the fear and anxiety associated with daytime leaks and make heavy periods less traumatic.

Knix Bras and Tops Review

Now to our Knixwear bra review. Knix manufactures four bra types, the wing woman contour bra, the evolution bra, the padded V-neck bra, and sports bras.

Before you start thinking about which type of bra you want, Knix offers a virtual fitting service, which you should out.

This free service allows one of the Knix customer service representatives to meet you over video chat to help you measure your bra size accurately. The only thing you’ll need is a soft measuring tape or a ribbon string and tape measure.

You’ll also find beneficial size charts on the Knix website.

All Knix bras are made with bonding technology, which makes them comfortable.

Knix WingWoman Contour Bra

With a plunging neckline and molded foam cups that lift and separate to give you great shape and definition, the wireless WingWoman Bra is a must-have.

Comfortable and lightweight the Wingwoman contour bra provides medium support, extra coverage on the side and back to prevent sideboob and overspill. Extra stretch in the band offers incredible comfort as the bra adapts to your shape.

This medium-supportive bra has an average rating of 4.4 stars based on 3402 reviews.

Customers share the bra is extremely comfortable, and have left the additional following comments:

  • This bra provides excellent support and profile;
  • The soft, silky woven fabric is a big hit, with customers remarking on how nice it feels next to their skin;
  • Numerous customers commented on how flattering the bra is.

Negative reviewers complained about the straps being too narrow and digging into their shoulders, along with complaints that the bras sizes being off.

Knix Evolution Bra Review

Knixwear’s Evolution Bra is a reversible, wire-free bra that provides 360-degree support. The bra is supportive, comfortable, and versatile. The bra is crafted from a quick-drying, odor-resistant fabric that will keep you dry all day and  This bra adapts to your unique shape thanks to its seamless construction and 4-way stretch fabric, and its higher neckline prevents spillage.

This is a highly versatile bra, priced at $55, you can flip it inside out and wear it in a different color or cross the straps to create a racerback.

The evolution bra has received an average rating of 4.3 stars from 4,172 reviewers.

Customers comment that the bra is an excellent everyday bra because it is lightweight, incredibly comfortable, and provides great support.

They also mention that it is an excellent alternative to underwire bras because it provides the same amount of support while being much more comfortable.

As with the other bras reviewed, customers expressed inconsistencies in the bras’ sizes, resulting in bras being the incorrect size and feeling uncomfortable.

These are good bras. I ordered 4 last year. This year I ordered 2 more of the same product and size. Unfortunately, it looks (and feels) like the sizing has either changed or the sizing is inconsistent.

One-star review @Knix.

Knixwear Sports Bras Review

Knix produces three types of sports bras:

  • Catalyst Sports Bra
  • Longevity Sports Bra
  • Luxelift Pullover Bra

Catalyst Front Zip Sports Bra

One of the most supportive Knix sports bras available, this front zip bra features an ergonomic zip that glides open smoothly and an inside flap that blocks out any sensation. The performance molded cups separate your breasts and firmly secure them in place, significantly reducing any movement and the adjustable band and straps ensure that you’re getting the right amount of support precisely where you need it.

With an average rating of 4.5 stars from 863 customers, this bra meets reviewers’ expectations once again.

According to reviewers, it provides excellent support, has adjustable bands, a comfortable front zipper, and is easy to put on and take off. Customers report that the bra feels tight at first, but gradually conforms to their shape.

Are Knix Bra’s Worth It?

As part of our Knix bra review, we’ve checked out what customers really think of the Knix bra. A large percentage of customers love their bras, with customers stating it’s the most comfortable bra they’ve ever worn, one even going as far as saying she forgot she was wearing it.

Knixwear bras provide excellent support and provide women with a great shape, as it molds to your body. The bras are invisible under your clothes, and you’ll be pleased that the majority of women reviewing the products stated they had no bulges or visible straps.

Knixwear Postpartum Review

I’m incredibly impressed with Knix’s postpartum selection. I wish these products had been designed when I was nursing my three children.

Not only do they produce leakproof nursing tanks, but they also offer high-rise underwear that flatters your new curves, leakproof pads to give you that extra security, and a pump-ease hands-free pumping bra.

Leakproof Nursing Tank

This wireless nursing tank bra features removable absorbent pads that provide leakproof protection and eliminate unsightly stains. It also has premium easy snap clasps that make feeding times much easier with one-handed access, and the built-in support works with your body to prevent any size fluctuations from becoming an issue.

To date, 291 reviewers have given the nursing tank a 4.5-star rating.

Customers praise the tank for being comfortable, flattering and for providing excellent support. The leakproof pads are perfect, and customers love not having to worry about leaking through onto their clothes.

I bought this tank in the nude and black. The tank is leak proof, flattering, and easy to nurse in. The only thing keeping it from five stars is that the black and nude seems to be made from different material.

The nude is scratchy and not as stretchy as the black and is oftentimes uncomfortable. If the nude fit and felt the same as the black, five stars all around. I still recommend the product as even the nude gets the job done; I just wish it was more comfortable. They do run small, so order a size up from your usual shirt size.

Three-star review @Knixwear.

Knixwear Shapewear Review

Knix’s latest range is the Shapewear range. It’s been designed to enhance and celebrate your natural shape.

Shapewear provides you with underwear that fits your body; you don’t have to squeeze yourself into this underwear; the brand will enhance all your curves. It does this by using the latest in fabric technology. The brand lets you be yourself and feel confident in who you are.

Knix Shaper Bodysuit

The Knix bodysuit compresses your front and back; the fabric hugs your body while smoothing and enhancing your natural shape. Featuring built-in wireless support for an unbelievable lift, removable padding for a great shape, and customizable, adjustable straps to complete your look.

This bodysuit currently has 15 reviews and a 4.5-star rating.

The shaper bodysuit has a medium compression level and is adjustable; it is incredibly comfortable, flattering, and fits like a second skin, to name a few of the compliments received.

This is more like a 3.5-star rating. I wanted to try out a full shaper bodysuit, so I gave this one a try. The good: the sensation of wearing it is close and supportive but not tight and restrictive. I liked the smoothing effect. The bra-back style hook and eye closure in the crotch gusset is much easier to deal with than my fears had led me to believe.

The bad: Length fit. Listen, I’m 170cm tall. That’s at the top end of average, but it’s still average. But there was simply not enough body length for me. The bra cups were way below my breasts, and there was nothing I could do about it, so my purchase price was a total loss.
Do I rec it: yes, but only if you are 160 cm tall or below.

Three star review @Knix.

Knixwear Reviews From Other Sources

As part of this Knixwear review, we have reviewed various websites to see what women say about the Knix brand.

On the Knix website, each product has a review element; some products have over 3,000 reviews and the majority for 4 out of 5 stars.

Here are what some of the customers are saying

This is my favorite of the Knix leakproof line. It’s somewhat higher cut than what I consider traditional boyshorts, but it has more coverage than the Knix bikini. It fits my body shape perfectly, so it doesn’t ride up.

taken from Knix website – this customer gave a 4 out of 5 rating

I like the fit and feel of this fabric, very comfortable, leakproof as advertised. I needed an underwear drawer overhaul and bought ten pairs and have used them daily for four months.

There are quality concerns though, the seams in the crotch are coming undone in several pairs. Quite frankly, I expect better underwear of this price that have been cared for according to manufacturer instructions. I have underwear that is far outlasting these that cost a fraction of the price.
