Period Underwear FAQs | EvaBody

EvaBody period underwear uses a four-layer protection system designed to absorb period fluid while helping you feel dry, comfortable and protected.

1. A moisture-wicking top layer draws fluid away from your skin.
2. An absorbent core captures and securely holds the fluid.
3. A leak-resistant barrier helps prevent fluid from reaching your clothing.
4. A soft outer fabric gives each pair the comfortable look and feel of everyday underwear.

The absorbent capacity and protective coverage vary between styles. Learn more on our How It Works page.

The absorbent gusset is slightly thicker than regular underwear, but EvaBody styles are designed to feel soft, flexible and comfortable without the bulky feeling of a disposable pad.

The thickness and coverage may vary according to the style and absorbency level.

Choose your absorbency according to your individual flow:

• Light Flow — for spotting, lighter days, discharge or backup protection
• Moderate Flow — for regular-flow days
• Heavy Flow — for heavier-flow days and additional protection
• Super Absorbency — for your heaviest days, overnight wear and selected styles suitable for light bladder leaks

Your flow can change throughout your cycle, so you may find that a combination of absorbencies works best.

Yes. EvaBody period underwear styles have been independently tested and confirmed PFAS-free. They are also made using OEKO-TEX® STANDARD 100 certified fabrics, which are tested for harmful substances.

This gives you additional confidence in the materials you wear close to your body.

EvaBody period underwear can generally be worn for several hours, but how long you can wear one pair depends on your flow, the absorbency level you choose and your individual needs.

EvaBody offers four protection levels:

• Light Flow — for spotting, lighter-flow days, discharge or backup protection
• Moderate Flow — for regular-flow days
• Heavy Flow — for heavier-flow days and additional protection
• Super Absorbency — for your heaviest days, overnight wear and selected styles suitable for light bladder leaks

On heavier days, check your underwear regularly and change into a fresh pair if you notice dampness or feel that it is nearing capacity. On lighter days, one appropriately matched pair may comfortably last from morning to evening.

Dampness can indicate that the underwear is nearing its absorbent capacity and should be changed. It may also mean you need a higher absorbency or a closer fit around the gusset and leg openings.

Change into a fresh pair and review the product’s absorbency and sizing. If the problem continues, contact us and we can help you choose a more suitable option.

Yes, selected EvaBody styles can be worn overnight. Heavy Flow and Super Absorbency styles generally provide the strongest protection, while some Moderate Flow styles may be suitable depending on your overnight flow.

Choose an absorbency matched to your needs and change into a fresh pair before going to bed. Individual wear time and capacity will vary.

Yes! Many of our customers use EvaBody underwear as a backup layer alongside a menstrual cup or tampon, especially on heavier days or for added overnight security. They work beautifully as a standalone product or as extra peace of mind when using other period products.

Selected EvaBody styles may also help manage light bladder leaks, discharge and everyday backup protection.

Suitability depends on the amount of leakage, fit and position of the absorbent panel. Check the individual product description before purchasing. EvaBody period underwear is not a substitute for professional medical advice or specialist incontinence products where these are required.

This depends on your flow, cycle length and how frequently you plan to wash them.

Many customers begin with three to five pairs. A larger rotation of five to seven pairs can make it easier to move through a full cycle without frequent washing, particularly because more absorbent styles may take longer to air dry.

Your underwear should always be completely dry before being worn again.

Before your first wear

Wash your EvaBody underwear on a cold or gentle cycle at a maximum of 30°C using mild detergent, then air dry completely. This helps prepare the absorbent layers for use.

After each use

1. Rinse in cold water until the water runs mostly clear.
2. Machine wash with similar colours on a cold or gentle cycle at a maximum of 30°C.
3. Use a mild laundry detergent.
4. Gently reshape and air dry completely.

Do not use fabric softener, bleach, dryer sheets or harsh stain removers. Do not tumble dry, iron or dry clean.

Read our complete Care Instructions.

With proper care, EvaBody underwear typically lasts between 6 months and 2 years, similar to regular underwear. Longevity depends on how frequently they are worn and how carefully they are laundered.

Following our wash instructions (cold rinse, delicate cycle, hang dry, no bleach or fabric softener) is the single biggest factor in extending their lifespan. Treat them well and they'll look after you in return.

Yes. EvaBody period underwear is designed to be worn on its own when you choose an absorbency suited to your flow.

It can also be worn as backup protection alongside a tampon or menstrual cup, particularly on heavier days, overnight or while you’re becoming familiar with your flow and the capacity of your chosen style.

Individual needs vary, so check your underwear regularly when trying a new absorbency for the first time.
