Approved by this grandma

Very discreet, looks and acts like every day undergarment. For light urge/dribble/leak. No pads needed. Washable, not bulky, undetectable under clothing. These provided the protection I needed and gave me the confidence to go about my normal daily activities. Highly recommended

These are a life saver!!! so worth $15

I used period underwear before, they were thongs from amazon. (love thongs bc I normally get sensory issues with more coverage) I always had a light period previously which the thongs were perfect for. Since getting a copper IUD, I have been bleeding through a regular tampon in less than an hour. I filled an ultra up within 5 hours. It says they soak up 12 regular tampons but I think they could soak up more tbh. These period panties are so comfy and they don't feel like I'm wearing a diaper, you can't see them through plants at all! I got a Medium which is my normal size in undies. For reference I'm 5'5 128-135 ibs, I wear size 2-4 pants, and small-medium shirts. They fit just how I wanted them to, they fit snug but not too tight, well the seams were a little tight so I ripped them a little by stretching them out with my hands. If you're like me and hate tampons and also worry about TSS absolutely buy these! I checked the Thinx website and the cheapest ones they had were $19, so these are definitely worth it. Comparing these to my old period panties they are amazing, no wet feeling when you out them back on, no stentch either!!! If you're on the verge of buying these just do it! life changing! I ordered 6 more right away lol.

Just try them.. you'll love it!

I was a bit worried because I've never tried a “reusable” pad before but THESE, THESE are the truth. Perfect for the beginning %26 end (especially at the end when I think it's done and BAM, SURPRISE!) I also love wearing these for overnight protection so I don't leak. I'll be buying these over pads forever now!
