Take a closer look at Knix vs Thinx period underwear

Many of you may have heard of the word “period underwear”, but have you ever actually do research to see what actually are they? We could say that period panties are underwear specially made for you to wear during “that time of the month”. 

Most of these period underwears work in a similar way: Using the multi-layers fabric particularly designed at the gusset to absorb menstrual blood. These undergarments can take the place of other disposable hygiene products such as pads or tampons. The most exclusive thing about these products is they are reusable, you can just wash them and re-wear them the next day.

Knix vs Thinx: Absorbency Comparision

As stated in an interview, Knix’s founder - Joanna Griffiths, they have various styles of period panties that hold different amounts of liquid. Depends on what item you are using, their underwear can absorb up to three teaspoons of leaks (which equals two tampons). There are many influencers who have tried these Knix products and they have come to an end that underwear can hold up to 14ml of menstrual blood. 

At the same time, Thinx underwear is said to have a little more absorbency comparing to the one from Knix’s. For example, the super-hiphugger line can absorb from 18 to 36ml, which is almost three regular tampons’ worth of flow.

Knix vs Thinx: Style, Colors and Size Comparision

Style and Colors

At first, Knix chose to launch the first three styles which are cheeky, bikini, and thong. Later on, they have developed more line-ups to fit every occasion such as boyshorts, highrise, etc. Knix once said that they do value quality over appearance, that’s why they tried to minimize their selection as much as possible. When you come to their website, you will mostly find some simple designs with basic and neutral colors, such as black, nude, or pink.

While with Thinx, we could say that Thinx has a wider variety of styles as well as colors and patterns to choose from. As for style, it should depend on your flow during your period. On your heavier days, you can choose the style that has high absorbency such as the super-hiphugger or the super hi-waist. Meanwhile. Other styles like Thong, Boyshort, or Bikini have less coverage and absorbency. They all come in different colors from neutrals like nude, black, gray to brighter colors like pink, purple or red.

Knix vs Thinx: Safety Comparision

Some people are still being skeptical about “period underwear” because lots of reports have shown that these can contain PFAS, which are chemicals that can be really dangerous if they’re added to the making process. Fortunately, Knix has got the jump on this issue by pursuing extra third-party for testing and happy to say that their products are PFAS free.

Meanwhile, Thinx has gotten into a lot of controversial issues due to this problem. It was when a scientist pointed out that Thinx underwear, especially the organic brief and the organic BTWN shorts had high levels of PFAS, which can cause many bacteria problems. But as soon as the controversy broke out, Thinx has shared the lab test results and claimed that there were no chemicals detected in their underwear.

Knix vs Thinx: Price Comparision

The only thing that makes people puzzled before getting themself a pair of this period panties is their price range.

A pair of Knix underwear can range from 23$ to 38$ while the Thinx one can be a little bit pricier, which is from 30$ to 42$.
