    Ok, but feel flimsy

    They are ok, I will use them but they don’t feel like a quality that will last very long.

    They have enough stretch to them that they aren’t binding anywhere but a sheer polyester feel to them that just isn’t my preference.

    Love these

    Of all the period underwear I've tried, these are probably my most favourite. Super comfortable and the absorbency is excellent. Haven't experienced any issues with leaking.
