    Product details

    The Full Week Kit: 7 cotton period briefs, 4 Noir and 3 Sage, all in the size you choose, plus a free wet bag. Ships free. Comes with the 60-Day Wear-Test Guarantee and one free size swap.

    A Single is one pair. The Everyday Trio holds 3 pairs, the Everyday Five 5 pairs and a free wet bag, and the Full Week Kit 7 pairs and a free wet bag. Every pair in a pack comes in the size you choose.

    Layers & absorbency

    The cotton top layer sits against your skin, the absorbent layers hold your flow, and a barrier layer keeps it off your clothes. Refer to the garment label for the full fiber composition.

    Wear it on its own on light to regular days. On heavier days, wear it as backup under a tampon, cup or disc.

    Care instructions
    • Rinse in cold water straight after wearing, until the water runs clear.
    • Machine wash cold on a gentle cycle, inside a mesh bag or the wet bag.
    • Hang to dry. Skip the dryer, fabric softener and bleach, which wear down the absorbent layers.
    • Keep 5 to 7 pairs, so a clean pair is always ready while others dry.
