Perfect
These are comfortable and I feel secure wearing them all day
Great product that works
The Thinx for All™ Women's Bikini Period Underwear is a standout option for those seeking comfort, reliability, and sustainability during their menstrual cycle. Designed with a three-layer gusset, it effectively wicks moisture, absorbs fluid, and prevents leaks, offering up to five regular tampons' worth of protection. This makes it a dependable choice for moderate to heavy flow days.  Comfort is a key highlight. The tagless cotton fabric and high-cut leg design provide a snug yet breathable fit, allowing for ease of movement throughout the day. Many users have praised its comfort and security, noting that it feels just like regular underwear. The underwear is also machine washable, adding to its convenience and eco-friendliness.  While some users have reported issues with leakage on their heaviest days,  the majority find it to be a reliable and comfortable alternative to traditional menstrual products. Its affordability and reusability make it a cost-effective and environmentally conscious choice. Overall, the Thinx for All™ Bikini Period Underwear offers a comfortable and practical solution for menstrual care, combining effective protection with everyday comfort.

They work great!
These are so great! I love wearing them for extra protection along with my flex disc. They're a little expensive, but worth it in the end. Make sure you buy enough to last you through your period.
