Great quality!
My wife loves these panties. She says they fit great, they are very soft and comfortable, and best of all they hold up very well when machine washing and drying. Now that she's put them to the test, I just ordered her more.

Comfy but wear quickly
Size: Large, Color: Organic Cotton 2 (5 Black)
These are perfect for every-day wear and i find them super comfortable. Mine are starting to tear and fall apart, which is more quickly than my other underwear, but I think its worth it for the price and comfortableness. I'll just replace them or repair them :)

Soft and True to Size
Size: Medium, Color: Organic Cotton( 5* Multi)
Comfortable and true to size these boyshorts are perfect. It's great to know it's safe material and organic and it holds up well in the wash. I would definitely buy again.

Comfy cute undies
One of the first things I switched out when I went on my non toxic journey, I really feel like they help my hormones balance and they’re so comfy

Falls apart after 5 wash cycles
Terrible. Do not buy. Only last 5 wash cycles before unraveling and falling apart. Also, uncomfortable as hell.
