Why choose Blinx menstrual knickers?

Collapsible content


Thanks to our cutting-edge LeakProof™ absorbent technology, our underwear will absorb your menstruation, leaks, or discharge without leaving any moisture or staining your clothes.


Experience your periods with peace of mind – no sensation of moisture, no leaks, and no odor.


No bulky feeling; enjoy an elegant design with a lace top, ensuring you feel stylish and confident.


Prioritizing our health, we've said goodbye to products with toxic ingredients. Your well-being is at the forefront of our design.


By choosing BLINX, you're contributing to saving the planet. Traditional hygiene products can harm both our health and the Earth. Join us in making a positive impact.

How does it work?

Introducing LeakProof™ Absorbent Technology:

Our revolutionary LeakProof™ technology comprises three layers to redefine your period experience. The first layer is designed to efficiently channel the flow, ensuring quick absorption. The second layer, a double-thick cotton structure, rapidly and continuously absorbs the menstrual flow while effectively neutralizing the natural scent of blood. The third layer, also double-thick, serves as a waterproof membrane, providing an additional barrier against leaks.

For the care of your Blinx, simply rinse it with cold water and toss it into the washing machine at 30°C. Keeping your period protection clean and fresh has never been easier. Embrace the future of menstrual comfort with Blinx and LeakProof™ technology.


  • Claire

    Absolutely thrilled with my Blinx knickers despite my very (very very very) heavy flow. They are comfortable to wear, very cost-effective, and eco-friendly!

  • Lilly

    Initially skeptical, Blinx knickers quickly won me over—no sensation of moisture or discomfort. I even wore them for a day out on a boat with no issues. I highly recommend them to everyone!

  • Angelina

    It's so delightful not to have an extra pad along with underwear; it feels liberating to sleep in any position at night, and there's no stress during the day.

  • Mary

    COMFORTABLE and ultra-absorbent! A day at work in sweltering heat, and not a single trace/stain/leak. I'm ordering 3 more to cover my entire week of periods.

  • Dhélia

    I love these panties! They are pretty, feminine, super comfortable, and most importantly, NO LEAKS!!! I can barely feel that I'm wearing them, and they are so elegant. You have to try Blinx! ✌️😘.

  • Maeva

    The Diana knicker is very elegant! It doesn't have a granny panty look, and the lace adds a refined touch to the design. They are invisible under clothes, and I have no leaks during my periods—a true re-vo-lu-tion!

Blinx: A Cost-Effective Alternative to Traditional Hygiene Products!

On average, a woman experiences around 450 menstrual cycles in her lifetime, spending approximately £7,302 on menstrual products from puberty to menopause (as per a Huffington Post study). This budget is significant for women, and Blinx knickers offer a solution to cut down these costs. When you purchase a pack of 6 knickers, each Blinx Knicker costs only £7 after the promotion and lasts 5 to 6 years. Say goodbye to the monthly expense of £4 to £5 on disposable tampons and pads! Plus, it's a significant reduction in waste for our beautiful planet. Blinx knickers are not only cost-effective but also environmentally friendly. Invest in your comfort and savings with Blinx.

Choosing the Right Size and Model Made Easy!

Our size guide is conveniently available on the product pages to help you select the perfect fit. Additionally, we offer collections tailored to different flow levels. Our recommendation? Always opt for the most absorbent models—better safe than sorry!

Blinx ensures that you find both the right size and the ideal level of protection for your unique needs. So, dive into our size guide, explore our collections, and embrace worry-free comfort during your period.

How Long Am I Protected?

BLINX Underwear provides up to 12 hours of protection, ensuring you can confidently navigate your day or night. Tailored to accommodate various flow levels, from light to heavy, these knickers absorb the equivalent of 5 to 6 tampons. This makes them perfect for extended use without worries about leaks or discomfort. Enjoy your day or night with the peace of mind that comes from 12 hours of reliable protection.

How Long Does a Knicker Last?

The lifespan of a BLINX menstrual knicker can reach 5 to 6 years with proper care. To maximize this longevity, it is recommended to wash the knickers at a temperature below 30 degrees Celsius, without using fabric softener, and avoiding the use of a tumble dryer. Air drying is preferable to maintain the quality and effectiveness of the absorbent fabric. By following these care tips, BLINX knickers remain reliable and comfortable over an extended period.
