What Absorbency Levels Does Knix Underwear Offer?

You can choose from four different absorbency levels:
- Super Absorbent underwear absorbs approximately eight tsp of liquid, equivalent to eight 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-absorbant underwear: This 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.
How Do You Wash Knix Period Underwear?
You may be wondering how to wash the Knix period underwear; well, Knix has made that easy as well; simply put them in your machine on a cold cycle with mild detergent and tumble on low heat.
It can be pretty daunting to change 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. One recommendation is to ensure you have purchase the right absorbency level for your menstrual flow.
Knix Period Underwear
For those of you, who are fed up with expensive, uncomfortable disposal pads or tampons, Knix period underwearcould work for you. Knix period underwear has three layers that keep you safe during your entire cycle.
- The first layer is an anti-odor top layer. This layer removes moisture from your skin, so your clothes don’t smell as bad.
- 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 option.
Knix 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.
Are Knix Super Leakproof Boyshorts Worth It?
Comfort
Customers have expressed their delight at the comfort of the extremely absorbent boy shorts. Customers praise them as soft and extremely comfy, as well as fitting well. According to one customer, they felt as if they were wearing nothing since they were so comfy. We did find one negative review that shared disappointment that the pad section was too far forward and was heavy.
Performance
The boyshort’s general performance was also praised, with buyers stating that they performed admirably on days of high flow and that they appreciated not having to worry about leakage. A few consumers discovered that they did not always last a full heavy day, but their periods were extremely 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).
There is moderate coverage through the hips and bottom, but the classic mid-rise silhouette has a gusset that is ultra-thin and absorbent. Its length ranges from about 7.5 to 8.5 inches.

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.

Comfort
One customer described the comfortable, light leakproof underwear as the best underwear they had purchased. Additionally, customers found the underwear to fit perfectly around their waists and legs, making them feel secure without digging in. One customer shared that the underwear can be worn anytime to help with sweat or small bladder leaks, and it made a huge difference in their comfort levels.
Performance
It was impossible to find a negative comment about the leakproof underwear’s performance, as so many buyers reported that the underwear absorbed all of their menstruation while also providing them with confidence throughout the day.
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.
Knix Bras and Tops Review
Now for our review of the Knix bra. Knix offers four different styles of bras: the wing lady shape bra, the evolution bra, the padded V-neck bra, and sports bras. Before you decide on the style of bra you desire, Knix offers a virtual fitting service that you should take advantage of.

Additionally, the Knix website has useful size charts. All Knix bras are constructed with bonding technology for added comfort.
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.

Comfort
Customers offered a variety of complimentary remarks regarding the wingwoman bra. In general, buyers praised the fit and comfort. Additionally, the bra provides superior support and comfort, and the soft, silky woven fabric is a huge hit with consumers who rave about how great it feels against their skin. There were a few unfavorable remarks, such as that the straps were too narrow and dug into their shoulders, and that many consumers got the incorrect size due to their mistaken belief that Knix bra sizes were incorrect. However, many of these women were very happy with how the customer service team handled their situation and with their new bras after that.
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. 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.
Is The Knix Evolution Bra Worth It?
Customers rave about how fantastic the bra is for everyday wear because it is lightweight, quite comfortable, and gives excellent support. Additionally, they state that it is an excellent alternative to underwire bras because it provides the same level of support while being significantly more comfortable. As with the other bras that were looked at, users found that the bras’ sizing was not consistent, which led to poor fit and discomfort.
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.
Is The Knix Catalyst Front Zip Sports Bra Worth It?
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 they mold to their bodies. The bras are invisible under your clothes, and you’ll be pleased to know 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.
Knix 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.
Is The Knix Leakproof Nursing Tank Worth It?
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. It features built-in wireless support for an unbelievable lift, removable padding for a great shape, and customizable, adjustable straps to complete your look.
Is The Knix Shaper Bodysuit Worth It?
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.
Three star review @Knix.
Do I rec it: yes, but only if you are 160 cm tall or below.
Knix Underwear 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.
