The absorption seemed super good. SUPER comfortable. I am so happy I gave these a try because so far they are making me a really happy customer.
I've tried several brands of period underwear, but this one stood out. The coverage was noticeably better—especially on heavier days. The fabric felt like higher quality compared to others I've used.
I wanted a boxer style for overnight. These were the only brand I found that actually used cotton in the gusset, which was very important in my search. I absolutely LOVE these. I have been converted.
For the first time in forever, I now have a reliable pair of period undies where I don’t need to have backup pads on hand. I can wear these with confidence all day long.
My period is pretty heavy and these did the job. They were comfortable and leak-free all day. Also really like wearing them at night as doesn’t “feel” like I’m wearing anything.
