Thinx earns polarized reviews: many report it works—comfortable, leak-preventing overnight and on light-to-moderate days with stylish high-waist, boyshort, and thong options—yet significant concerns surface. Reviews cite PFAS scandals, inconsistent sizing and fit, lingering odor, limited absorbency and edge coverage for heavy flow, bulk in higher-absorbency styles, and durability issues like fraying elastics and seams.

    I used to love this brand but they had some news spread about them about forever chemicals so I am hesitant to continue to use them; however they were great underwear to use while on period. However I used them more as insurance along with pad or tampons!

    These are the best! I’ve been struggling to adapt to having my period again after having my IUD removed and Thinx has been an incredible and unexpected solution. I love the comfort and confidence they give me you get through the day (and night!) without worrying about a leak. I’ve tried other brands, but I keep coming back to Thinx

    I'd been buying their products for my teen. I recently purchased a few more but newer ones don't have lining. I'm very disappointed and won't go back.

    As far as period products go, these are a massive upgrade from pads, tampons, or cups in my opinion. For a girl who’s just starting to get her period, these are a far better option than having her figure out the period-care logistics of disposable products, and I wish I’d had this option then. There are some downsides though: they had some scandals a few years ago involving materials and business practices, and their elastic especially hasn’t held up as well as other similar brands I’ve used over the years. They also aren’t great for traveling, and will take away the camaraderie of being able to give another woman a tampon when she needs it, but these are minor, fixable issues.
