Spotting and overflow can occur for all kinds of reasons, like bladder control issues, post-postpartum recovery, sex, and – of course – menstruation.

Spare Pair is a pair of seamless bikini-cut underwear made of eco-friendly, biodegradable fabric.

They come in a pouch designed to hold your Spare Pair underwear for emergencies, and your used pair once it's time for a switch. Change them out, reseal the package, and take them home to wash. The package is waterproof.

These do run a bit small, so we recommend going up a size if you are between sizes.
