Period & Leak-Proof Underwear

Need a little extra reassurance on busy days? Our Period & Leak-proof Underwear is made with fast-absorbing leakproof technology to help handle everyday leaks, and it is finished to be 100% PFAS and silver-free. Each pair is machine washable, so you can pop them in the wash and wear them again with less waste and more ease.

 

Boody period underwear for women is breathable and soft, crafted from viscose made from organically grown bamboo for that signature gentle-on-skin feel. The main fabric combines 79% viscose with nylon and elastane for stretch and shape retention, while the gusset is crafted from 100% cotton for natural comfort.

Period Pants in Full Briefs, Undershorts, Bikinis & Thongs

Our Period & Leak-Proof collection includes 5 styles and 4 absorbency levels, designed to suit every body and every flow. Choose from our best-selling Thong for a barely-there feel, to the low-rise, cheeky Hipster Bikini, low-rise full bum coverage Classic Bikini, and Full Briefs and 3" Undershorts when you prefer extra coverage in your period knickers.

 

With options for light, light-to-moderate, moderate-to-heavy and overnight flow, you can switch up your period pants depending on the day and what you are wearing. Mix and match styles to build a rotation that supports you through every stage of your cycle.

 

Comfort is built into every detail. Expect a wide, soft waistband, a buttery-soft bamboo feel and a breathable, odour-resistant design, without the stiff synthetic sensation or bulky padding you might be used to. These underwear are made to sit smoothly under clothing and move with you, so you feel comfortable and confident from morning to night.

Frequently Asked Questions

Period pants are a reusable alternative to disposable pads and tampons, worn like regular knickers with the absorbency built in. Boody holds liquid in a discreet multi-layer gusset, so there is no bulk and nothing to throw away. Many people wear them alone on lighter days and as backup on heavier ones.

Yes. Boody period pants are OEKO-TEX® STANDARD 100 certified and have been independently tested by TÜV Rheinland in Germany to verify zero traces of PFAS, the "forever chemicals" sometimes used to make textiles water-resistant. The leak-proof layer performs without them.

Boody period pants can be worn for up to 8 to 12 hours, depending on your flow and the absorbency of the style. On lighter days a single pair covers a full day or overnight. On heavier days, change more often or wear them as backup with a tampon or cup.

Period pants work through absorbent layers built into the gusset: a moisture-wicking top layer moves liquid away from the skin, an absorbent core holds it, and a leak-proof barrier stops it reaching clothing. Boody builds this into soft bamboo viscose, so they stay breathable and look like regular underwear. To learn more, read our guide to How Period Underwear Works.

Rinse period pants in cold water after wearing until the water runs clear, then machine wash cold on a gentle cycle in a mesh laundry bag with similar colours and a mild detergent. Avoid fabric softener and bleach, which reduce absorbency and break down the absorbent layers, and air dry away from direct sunlight rather than tumble drying.
