Kind %26 Comfy

My partner really likes these. Sizing chart called for a 3x but it wasn't available. 2x fit perfectly. Sizing chard was definitely good guidance. They look good %26 she's comfy. Also got her the thong one and she found that very comfy as well. Only thing she wishes they were cotton but I'm not sure if that would work for period underwear. Red %26 pink color is nice. 39 waist, 54 hips

Easiest thing out there for women

These period panties are extremely comfortable. Heavy flow with no leaks, also I didn't use a back up method like a pad, cup or tampon either. They are so soft. I have a bad reaction to all tampons and pads, even if I use organic. So these period panties were a walk in the park compared to other options.

Goodbye bulk, hello confidence

These period panties have been a total game changer for my teen! She has a very heavy flow, and these have been so much more comfortable and confidence-boosting than relying on bulky disposable products. They're soft, absorbent, and stay in place all day without leaks. She loves that they look and feel like regular underwear, so she doesn't have to worry about feeling self-conscious at school or during activities. They're easy to wash, hold up well, and have made that time of the month so much less stressful. Definitely one of the best purchases we've made!
