Reusable leakproof underwear that handles a moderate period on its own, built on a four layer core inside a seamless black bikini brief.
The fabric is thin and stretches like regular underwear. There is no bulk through the gusset, no crinkle when you move, and the leg openings and waist are laser cut so nothing prints through leggings or a fitted skirt.
Four layers do the work. The layer against your skin pulls moisture in one direction, so it stays dry instead of holding wet fabric against you. The middle layers absorb and hold, and control odor while they do it. The outer layer is a breathable waterproof barrier that keeps everything off your clothes.
Moderate is the middle of a three level absorbency scale, which covers most days of a normal cycle on its own. On the heaviest day or overnight, wear it as backup under a cup or a tampon.
Rinse in cold water, wash on a gentle cycle, hang it to dry, wear it again. A matching drawstring pouch comes in the tube for carrying a spare, or carrying a used pair home.

Care
Rinse in cold water by hand first, then machine wash on a gentle cycle and hang to dry. Skip the dryer, the iron, fabric softener and bleach. All four break down the waterproof layer and shorten the life of the pair. Do not wring it out. Store it dry and out of direct sun.
Use it for
Regular flow days on their own, backup under a cup or a tampon on the heaviest day, overnight, long travel days when changing is inconvenient, workouts, and the day or two before you expect to start. A pair also works for spotting between cycles and for light bladder leaks.
FAQ
Can I wear it without a tampon or a pad? Yes, that is what moderate absorbency is for. Most people wear it on its own for the bulk of their cycle and add backup only on the heaviest day.
How long can I keep it on? Up to twelve hours, depending on your flow. Change it sooner if it starts to feel damp against your skin.
Will it show under clothes? No. It is seamless with laser cut edges and no thicker through the gusset than regular underwear.
Does it hold odor? The absorbent layer is treated to control odor, and rinsing in cold water right after wearing keeps it fresh between washes.
How do I wash it? Cold rinse by hand, then a gentle machine cycle, then hang to dry. No dryer, no fabric softener, no bleach.
How many pairs do I need? Two or three covers a full cycle if you are washing along the way. Five or more and you can go a whole period without doing laundry mid week.
What size should I get? Take your usual underwear size. The fabric has a lot of stretch, and sizing up does not improve the fit, because the seal at the leg opening is what stops leaks.
Will anyone know what is in the package? All orders from The White Unicorn ship in a plain package, and the return label will read TWU or shipping department.
