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.

Grandma's helper - Amen

I have sudden urges and will “dribble” small amounts en route to commode. This underwear garment provides the absorption, protection, and privacy I want. They look like regular panties. I wear the same pair sunrise till bedtime. I previously used a pantyliner, which doesn't absorb, maybe changing once a day, I didn't like the dampness against my skin. I never experience any feel of moisture using these briefs, there's no bulky feeling, no odor. I have washed at least 15 times, air drying, and they look, feel, and perform like they're new just out of the box. Fit is perfect and don't lose their shape. Still do my Kegels, combined with wearing this garment, and I'm happy.

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
