Full-Coverage Comfort. Feminine Detail.

Heavy-flow protection can still feel soft, flattering and easy to wear.

The EvaBody Heavy Flow Cotton Lace Boyshort combines a soft cotton-rich body with a secure, full-coverage fit through the hips, back and upper thighs. A delicate lace waistband adds a feminine finish, giving you dependable protection in a style that feels more elevated than traditional period underwear.

Designed for heavier-flow days and overnight wear, it offers reliable absorbency to help you feel dry, comfortable and confident for longer. The stay-put boyshort silhouette provides added coverage and reassurance, making it a practical choice for busy days, sleep or whenever you want a little more support.

It can also be worn for light bladder leaks, discharge or times when you need added backup protection. The current product specifications confirm heavy-flow absorbency, a cotton-rich body, full coverage and a lace waistband.

Soft comfort. Secure coverage. Protection with a feminine finish.

  3. Do not use bleach or fabric softener.

Perfect for overnight confidence

I bought these specifically for sleeping because I always worried about overnight leaks. They've been incredible. The extra coverage gives me so much confidence and they're surprisingly soft and breathable. I wake up feeling dry and comfortable every time.

My new go-to for heavy days

I didn't realise how much mental energy I was spending worrying about leaks until I started wearing these. The boyshort style gives amazing coverage without feeling bulky, and the lace waistband makes them feel so much nicer than I expected. I wore them on my heaviest day during a full day at work and completely forgot I was even on my period. No leaks, no discomfort and no constantly checking my clothes. They wash beautifully and still look brand new after several wears. EvaBody has genuinely changed my monthly routine, and I'll never go back to disposable products.

Comfortable from morning to night

These are exactly what I was hoping for. The fabric is really soft, they stay in place all day and don't ride up like some boyshort styles do. The lace waistband is a lovely detail and makes them feel much more premium. I'll definitely be buying another pair.

Better than I expected

I wasn't sure about trying period underwear for the first time, but these really impressed me. They're supportive, comfortable and the absorbency is exactly what I needed on heavier days. The only reason I'm giving four stars is because I'd love to see even more colours, but the quality is excellent and I'd happily recommend them.

Great for busy mums

As a mum of two I'm constantly on the move and don't have time to worry about changing products every few hours. These have been amazing. They're comfortable enough to wear all day, give fantastic coverage and have made my periods so much less stressful.

Great coverage, just a little warm for summer

The protection is excellent and they're soft to wear. I personally prefer less coverage in warmer weather.

The lace detail is beautiful

The lace detail makes them feel feminine instead of purely practical.

C

A boyshort that actually looks pretty
