    High quality

    Love that these are thick, but not too thick. They feel high quality and are soft and comfortable to wear, but still keep a sleek profile under clothes.

    So comfy

    After 30 years of wearing one brand of underwear I switched over to organic fabric. I am so pleased with these undies!!

    perfect fit, long-lasting

    I've been wearing low-rise bikinis from Subset for about 5 years (since they were called Knickey) and still have pairs that are in great condition. I love all the underwear I've purchased, it's comfortable and the quality really holds up. The 3 pack I just bought fits just as great and seems like just as good quality as all the others!

    comfy

    I love these! I like that the inside seams are sewn down, and the way the crotch is is comfortable too.
