What Women Are Saying
Pairs Well With
The Keep it Brief, Brief
How Do The Clasps Work?
The Keep it Brief, Brief features six soft, adjustable hook-and-eye closures on each hip. When it's time to change, simply unhook the sides and the underwear opens completely flat, allowing you to remove it without taking off your pants or shoes. Drop the soiled pair in our waterproof, smell-proof Travel Bag, swap in a fresh pair, fasten the clasps, and you're on your way.
Designed for quick, discreet changes wherever you are, the side-opening design makes changing period underwear as easy as changing a pad... without noisy wrappers or adhesive.
What Do I Do With The Worn Pair When I'm Out?
That's exactly what our Travel Bag was designed for. The waterproof, smell-proof bag carries a clean pair and holds the worn one until you're home, so changing on the go stays quick and discreet.
Can I Sleep In The Keep it Brief, Brief?
The Keep it Brief, Brief is designed for daytime wear. It can handle a light night, but for overnight protection we recommend The Shortie (Heavy Flow), which carries our maximum absorbency and padding all the way up the front and back.
Does It Feel Bulky Like A Pad?
No. All four layers are sewn into a single smooth gusset that feels like regular underwear. There's no shifting, no bunching, and nothing to reposition during the day.

Her Pair has you covered. If your first order fits differently than expected, exchange it for a new size, free, within 45 days. Worn pairs are welcome. That's the only honest way to know your fit. Head to Exchanges to start a swap.
