## Emma's take

All-day leak protection that fits like plain, comfortable underwear.

Moderate flow sits in the middle of UVA's three absorbency tiers, and Medium is the size most bodies reach for first. The 4D LeakBlock layers are built to absorb, wick, and seal in one thin stack, so the outer fabric reads as ordinary underwear rather than medical gear. It's designed for a full day of moderate flow, not a heavy one, so this is the pick for regular cycle days, not your heaviest. If your flow runs heavier some days, pair it with a light backup, and wash promptly after wear so the layers keep performing.

## Frequently asked questions

## How long can I wear UVA Moderate Flow period underwear before changing?

The Moderate flow tier is built for up to 12 hours of protection depending on your flow that day. Most wearers plan on one change around the halfway point of a busy day, then again before bed.

## Can I wear these during workouts, sleep, or travel days?

Yes. The ultra-thin, breathable fabric is designed for exactly that range: work, exercise, sleep, and travel, without added bulk under leggings or fitted clothes.

## Do I need a backup pad or tampon on heavier days?

Moderate flow underwear is built for regular-to-moderate days, not the heaviest ones. If your flow runs heavy, pair it with a light pad or tampon for extra peace of mind.

## How do I wash period underwear to keep the leak protection working?

Rinse in cold water right after wearing, then machine wash cold on a gentle cycle with no fabric softener or bleach. Hang to dry instead of using the dryer to protect the waterproof TPU layer.

## Will Medium fit the same as my regular underwear size?

The stretch nylon-elastane blend is built to fit like everyday underwear rather than medical wear. If you're between sizes, sizing up is the safer call for all-day period wear.
