    Seamless

    These are a life saver! i’d have 20 if i could, they are perfect if you are on your period and still want to wear something tight as you do not see the outlines! These are perfect when wearing a pair of tights or dress and not having to worry about a pad

    Finally, undies that work under leggings

    For so long I dreaded getting my periods and going to pilates. I would constantly skip classes and lose money before I just couldn't deal with the stress of leaks and the lines under leggings. Now I have these period underwear, I haven't missed a session. Thanks Fanzy Pantz. Love you guys.

    Love that there are no seams under my leggings

    I've always hated wearing period underwear to the gym because there was an ugly line under my leggings. Now I can wear these seamless undies and it's gone. I feel so much more confident now and knowing I'm not going to leak when I'm doing squats means I can focusing on lifting weights, instead of stressing about seeing a mark on my pants. They also feel like Skims. They are quite low at the front though so I can't put the heat patch on them but I still love them.

    Seamfree is great

    I like these undies, it's seamfree and comfy. The back part is a little bit looser for me and the front is a bit lower than I would normally like but I still find them extremely comfortable and work well during pilates.
