    So happy

    I sweat a lot. I just do. These help me out so much. I feel super confident when wearing them. After I tried out an initial pair, I immediately came back and ordered 6 more.

    I do think that they run a little small. I don’t like my underwear being tight at all, so I ended up getting a size that’s about 2x bigger than what I normally get. The band at the top is slightly tighter than I imagined. I’m about 5’6”, 140#, and I got the XL. But again, I don’t like my panties being tight at all, so I’m probably a bit more particular than most.

    Anyway, thank you for making these! I’m obsessed.
