Reviews Summary
Customers say these thongs are comfortable and lightweight, with many finding them perfect for light protection and gym wear. Many reviews mention sizing inconsistencies, with most recommending sizing up as they tend to run small and fit tighter than expected. Common feedback includes praise for the comfortable feel and confidence they provide. Some note concerns about the protective liner placement, with a few mentioning it doesn't extend far enough back or causes gapping in the crotch area. While most appreciate the no-show design and leak protection, some find the edges dig in or the waistband sits too low. Reviews are mixed on durability, with some reporting stretching over time.

    Love these no show thong

    Loving these had a bay last year and tampons don’t feel great right now and these have been a lifesaver when I had light periods after getting an iud. Can wear all day without a second thought and they feel great.

    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.
