Seamless Comfort. Reliable Protection.
Period underwear should work with your wardrobe, not against it.
The EvaBody Moderate Flow Seamless Mid-Rise Cotton Bikini combines a soft cotton-rich body with a smooth, barely-there finish designed to sit discreetly beneath clothing. Its mid-rise fit feels secure and comfortable, while the cheeky back offers a sleek, modern silhouette with less visible bulk.
Designed for moderate-flow days, it provides dependable absorbency to help you feel dry, protected and confident throughout the day. The seamless construction helps reduce visible lines, making it an easy choice under fitted outfits, workwear, activewear and everyday clothing.
It can also be worn for discharge, light bladder leaks or whenever you want discreet backup protection without sacrificing comfort.

I spend all day in tailored work pants and wanted something invisible underneath. These are exactly what I was looking for. Comfortable, reliable and they don't move around during the day.
I've tried a few brands and these are by far the most comfortable seamless style. They absorb well and look great too. The only reason for four stars is I'd love to see a nude colour added to the range.
If nobody told me these were period underwear, I honestly wouldn't know. They're soft, stretchy and so comfortable. The seamless finish makes such a difference under fitted clothes.
I wear these for Pilates and walking, and they're fantastic. No digging in, no lines and no bulky feeling. I felt comfortable and confident the whole time.
I bought these because I wanted period underwear I could wear under leggings and work trousers without visible lines. They exceeded every expectation. They're incredibly smooth, stay perfectly in place and genuinely disappear under clothes. I almost forgot I was wearing period underwear, yet I still felt completely protected all day. They're comfortable, lightweight and flattering, and I've already ordered more. EvaBody has absolutely nailed this design.
I'll definitely be purchasing another pair because these have worked so well for me.
They feel cute, comfortable and don't look like traditional period underwear.
This was my first EvaBody purchase and I'm genuinely impressed by how comfortable and practical these are.
I completely forget about these once I put them on, which is the best compliment I can give.
Discreet, dependable and surprisingly comfortable.
These are ideal for workdays when I need something reliable and comfortable.
The fabric feels lovely against my skin and doesn't irritate me at all.
The quality is really good and they do exactly what they're meant to do. The fit was just a touch firm on me.
Comfortable enough to wear for long days and commuting.
The mid-rise fit is just right for me, not too high and not too low.
This pair has become a staple in my monthly rotation.
I specifically bought these for fitted outfits and they work beautifully.
The seamless finish is fantastic and feels invisible under clothes.
Very comfortable and well made. I would size up next time just for personal preference.
They've made my moderate days much less stressful.
These strike the perfect balance between feeling protected and not feeling bulky.
The mid-rise cut sits perfectly on me and doesn't roll down.
I wasn't expecting to love these as much as I do.
Really nice quality and fit. I'd just love to see a few more colour options available.
I can wear these all day at work and still feel comfortable by the evening.
This bikini style is the perfect combination of coverage and a flattering fit.
I honestly forgot I was wearing period underwear because they're so comfortable.
Soft fabric, comfortable fit and very lightweight.
No lines under leggings or fitted dresses which is exactly what I wanted.
The absorbency is great for my moderate days. I just wouldn't use it for my heaviest day.
The cheeky cut is much more flattering than I expected and still feels secure.
A really practical style that still looks and feels like regular underwear.
I wore these for a busy day running errands and forgot I was even on my period.
