Reemi Period Underwear - High Waist; Night

These period undies are designed to be a hygienic, easy and comfortable way to care for yourself and the planet while you’re bleeding.

Our sustainable closed-loop Modal makes them super soft on your skin, while CottonX™ is a natural smart fibre that provides self-disinfecting benefits. Our layer system makes them super absorbent so you don’t need to worry about leaks.

The High Waist style sits up around your natural waist. Our waistband for our black underwear is a soft black elastic which has a slight sheen to it. For our green underwear we use the same elastic, but this is covered by the soft Tencel™ Modal to create a green on green colour palette. Both waistbands provide security around the waist and won’t lose their shape or stretch out over time - perfect to hold you in while you’re menstruating.

You can choose between two colours - green or classic black. For our green underwear, the gusset is lined with black fabric on the inside to avoid any discolouration after use. Our black underwear is black throughout.

Our Night style is our most absorbent period underwear, designed to last you all night with our extended leakproof gusset. These are currently being lab tested, but know that these are our highest absorption option, so if you've got a heavy flow this is the one for you. The Night Time style is specifically designed for nights, but can also be worn during the day for those with heavier flows - they just aren’t quite as slimline as our Day Time style. You can also pair with a cup for a 100% zero-waste and leak-proof period.

When you buy Reemi you’re supporting period equity globally - all proceeds from sales of Reemi Period Underwear go toward sustainable menstrual products and education for people in Bangladesh.
