        • No backup required - no need for a menstrual cup, tampons or other backups.  Test them out at home first and see how long you will get out of them, but generally, you will get at least 6 hours and up to 12 hours. Everyone is different.  We do not recommend wearing them for longer than 12 hours for hygiene reasons.
        • Easy to wash - just rinse them in cold water until the water runs clear, then dry pail or soak in cold water until ready to wash.  Wash by hand or in a wash bag in the machine - in cold or warm (30 degrees max) water.  Wash with similar colours. Hang dry. 
        • Try them on over your regular clean underwear before use to check the fit. Then give them a wash before wearing.  Washing first primes them and improves the absorption performance.
        • Fits True to size - select your usual underwear size.  

        Do I wear these with a tampon, cup or pad?

        Eco briefs are a complete replacement for other leak management products. There is no need to use anything else in conjunction with them, even on your heaviest days, with our heavy and super absorbency briefs holding up to 60 ml.  If you do like to wear a menstrual eco cup, you can choose light or moderate absorbency underwear, to wear as a backup for when your cup overflows.  Refer to our Know Your Flow page, for more guidance. 

        Eco pads are also a complete replacement for other period and lbl products, with 4 layer Eco-tech designed to provide absorbency up to 100 ml.

        What size is right for me?

        We recommend taking your normal underwear size. 

        Do I need to wash them before wear?

        Yes, we recommend washing your period underwear and eco pads before the first time you wear them to help prime the 4 layer eco technology. 

        What does it feel like wearing them?

        Our eco briefs feel just like regular underwear! The absorbent gusset was designed to be comfy and discreet, never bulky or heavy. Just choose your favourite style of underwear and you are good to go! 

        Eco Pads are soft and comfortable and clip into your regular underwear to keep them in place.  They use ‘dry touch’ technology to keep you feeling dry, even with heavy flows.  Please monitor and if you start to feel ‘wetness’, please change your eco briefs or eco pads. 

        To determine your size, there are two ways to check:

        1. Measure your best fitting underwear or swimwear at home against the 'Half waist Flat Lay' measurements.  This is the dimension of the top of the waist band of your underwear, when they are lying flat.

        2. Measure around your hips, so over your hip bones and check against the Hip measurements either below or on the specific size chart for your product.  

        If there is a discrepancy between your hip measurements and your flat lay measurements with our size chart, go with the flat lay measurements, as they represent the actual underwear you are buying and will be more accurate.

        Always refer to the product specific size chart if there is one available (found at the top of the product page above the size selections), otherwise, refer to this chart below. If in doubt, please message us on chat function or email and we can discuss your needs. 


        How to measure

         To choose the right size, follow the tips below:

        • Use a flexible measuring tape for maximum accuracy.
        • Measure hip dimensions on bare skin or over thin, tight-fitting fabric.
        • For flat lay half waist measuring, take the measurement of the garment when unstretched, and be mindful or how stretchy the elastic is of your sample, as very stretchy elastics will be designed to stretch out, so give some allowance for that.

        Cycle Saver Bundle - Very happy with these. They are comfortable to wear and keep me feeling dry.


        First Period Pack - This is a great value pack, with 4 pairs of undies and eco pads. Love the bunny water bottle.. very cute and my daughter loved the ruby charm bracelet too. I researched other brands packs and this is definitely the best value. Seem to be the best quality underwear too.
