I've tried quite a few period underwear brands over the years, but this is easily my favourite pair. I bought these for my heavier days and was honestly surprised by how secure they felt without being bulky. I wore them all day at work and overnight, and had absolutely no leaks or discomfort. The high-waisted fit is really flattering and stays in place, and I love the mesh detail because it makes them feel stylish rather than looking like period underwear. They're soft, breathable and genuinely comfortable enough to forget you're even wearing them. EvaBody has completely changed how I get through my period. I no longer stress about leaks or waking up in the middle of the night to check my sheets. I'll definitely be ordering more.
Poor quality. Elastic is loose and fabric cheap. First time purchasing evabody underwear and won’t be purchasing again due to cheap quality. Overpriced for what it is.
Hi Joanna, thank you for your honest feedback. We’re so sorry your first EvaBody purchase left you disappointed. We want you to feel comfortable and confident in our underwear, and we’re sorry this wasn’t your experience.
Your concerns about the elastic and fabric matter to us. We’ll contact you directly today to help arrange a refund or replacement, whichever you prefer.
I love that these actually look elegant. The mesh panels make such a difference and the absorbency is excellent even on my heaviest day. I've already ordered another pair.
These gave me so much confidence during a long work day. No leaks, no shifting and they still looked really flattering. EvaBody has definitely won me over.
Really impressed with the protection and comfort. The only reason for four stars is that I wish there were even more colours available. Otherwise they're excellent quality and I'll buy again.
I used to double up with other products overnight but not anymore. These kept me dry all night and were incredibly comfortable. The high waist is so supportive too.
I bought these before travelling and they were amazing. I had a heavy day while flying and felt completely protected. The mesh detail is beautiful and they don't feel bulky at all. Worth every dollar.
Really happy I gave these a try. They exceeded my expectations.
The mesh design is such a nice touch and they feel very high quality.
These have become my overnight go-to pair.
Great coverage without feeling bulky or restrictive.
I wore them on a busy day out and forgot I was even on my period.
I love the look of these. They don't feel clinical at all.
The fabric is soft and supportive and the absorbency is excellent.
I love that they're practical but still feel feminine.
I can finally sleep without worrying about leaks or stains.
The high waist makes me feel so secure on my heavy days.
Really good protection and comfort. I would just love to see more colour options.
These stayed in place all day and didn't dig in anywhere.
The fit is amazing and I love the extra coverage around the hips and back.
I've already ordered another pair because I keep reaching for these.
They work really well, I just personally prefer a slightly lower rise.
I didn't think such a sleek style could be this absorbent.
They look more like nice everyday underwear than period underwear.
These are expensive but absolutely worth it for the peace of mind.
I was looking for stronger protection and these delivered.
I felt secure wearing these all day at work and didn't need to think about my period.
This has quickly become my favourite style from EvaBody.
I expected them to feel bulky but they're actually really comfortable.
The high waist is really flattering and the mesh detail gives them a premium look.
No leaks overnight which is huge for me. I slept so much better.
The mesh panels make these feel so much prettier than other period underwear I've tried.
Finally found a pair I can trust on heavy days without needing extra products.
