Because of these materials, it can hold almost 1/4 a cup of liquid, while still leaving you feeling dry and comfortable all day long. ONDR is tested regularly by independent laboratories to ensure they are 100% free from PFAS.

Save The Planet with Thinx, Knix & ONDR


With single-use leak proof protection options (panty liners, tampons, pads, diapers, etc), the amount of waste is staggering. Women typically use products like this for more than 40 years, which ends up being a lot of waste. With leak proof undies, you can wash and reuse over and over again without losing absorbency, and the planet says thank you! All three brands discussed in this article are washable and reusable, so you can feel good about doing your bit to minimize your footprint. 


ONDR goes one step further to connect with mother earth with revolutionary plant based liner technology. Move freely and with confidence with the odor protecting, leak proof liner that is sourced from algae and other plant materials.


Whether you choose Thinx, Knix or ONDR, you’re one step closer to freedom and confidence during your period and incontinence moments. Hopefully with this guide you can choose your first pair based on what you care about most.
