Period underwear | Serene | Organic cotton


Feel comfortable and empowered wearing soft organic cotton period undies. 

Heavy flow  

Suitable for use all day or night. Super absorbent, underwear can hold: 40 ml, 3 to 4 pads worth.

No leakage

Four layers of protection. Antimicrobial, moisture-wicking and a leak-resistant barrier. 


Soft, breathable natural organic cotton fabric and no nasty smells. 

Other uses: great for use postpartum or for mild incontinence. 

Benefits: washable and reusable. Less need for ‘disposable’ single-use pads/ tampons meaning less waste produced across NZ.

Easy care instructions: after use, rinse under a cold tap, normal cool wash (ideally in a laundry bag), line dry then wear again!

Unsure on size?  If in-between sizes we recommend selecting the smaller size for protection from leakage. 

New to period underwear? We recommend when using the undies for the first time, try a couple of hours at home and then gradually increase the wear time as your confidence grows! Follow our blog via Instagram @bumbling_nz for hints and tips and other low waste alternatives.
