Pocket Pants – Leakproof Postpartum Underwear with Built-In Heat Patch Pocket

For leaks, recovery, and everything in between.

Fanzy Pantz Pocket Pants are designed for the realities of pregnancy and postpartum, from third-trimester bladder leaks to post-birth bleeding. Whether you're still carrying your bump or deep in newborn life, these undies offer leakproof support without sacrificing softness or style.

They sit comfortably under the bump, making them perfect for pregnancy wear, and won’t dig in or irritate tender post-birth bellies.

Fabric & Fit:

Made from a high-quality polyamide and elastane blend, these undies are soft and smooth against sensitive skin, stretchy and flexible as your body changes, wrinkle-resistant, quick-drying, and colourfast. They are long-lasting and maintain their shape even after many washes.

Built for Mums. Designed to Perform:

The multi-layer leakproof gusset absorbs up to four regular tampons' worth of fluid. No bulky pads, no stress.

A discreet built-in heat patch pocket is perfectly positioned for soothing relief over your lower abdomen or perineal area.

The under-bump cut offers a comfortable alternative to high-waisted styles.

Reusable and washable, these are better for you and better for the planet.

Why You'll Love Them:

Wear before birth for bladder leaks and bump comfort.

Use postpartum for bleeding, cramping, and recovery care.

Tuck in your hospital bag or keep a pair stashed in your pram.

Pair with our soothing heat patches for targeted comfort on the go.

No mesh. No liners. No disposables. Just wearable, leakproof calm wherever motherhood takes you.

Fanzy Pantz underwear is made to be soft, supportive, and secure — with full coverage that keeps you feeling fresh day and night.

We’re always happy to help—just reach out!

Fanzy Pantz are made to be reused, loved, and worn again and
again. Caring for them is simple:

Rinse in cold water after wearing, until the water runs clear.

Machine wash on cold in the included laundry bag with similar colours.

Skip the fabric softener or bleach — it can affect absorbency.

Air dry flat (not in the dryer) to keep the layers performing their best.

💡 Tip: Have a second pair ready to rotate while one is washing and drying.
