Frequently Asked Questions

Not at all. The mint used in piper & mint products is a botanical woven directly into the fabric for its cooling and freshness properties — not for scent. You won't smell it, and it contains no oils that transfer to your skin or have any effect on milk supply.

The menthol naturally present in mint interacts with your skin's temperature receptors to create a genuine cool-to-the-touch sensation. It's not just a feeling — the fabric is engineered to stay cooler against your skin compared to standard cotton, bamboo, or modal.

Bamboo and standard modal are soft and breathable, but neither has built-in, lasting cooling properties. Our mint-infused viscose adds active cooling, moisture-wicking, and natural odor resistance that standard fabrics don't always have. It's also known for higher breathability and a softer touch than bamboo.

Yes. Our mint-infused fabric is gentle and non-irritating, with no harsh chemicals or synthetic cooling agents. It's been worn comfortably by people with sensitive skin, including postpartum moms and those managing skin changes during perimenopause.

No. The mint infusion is woven directly into the fiber — it's not a topical treatment or finish that washes away. Our fabric has been tested to retain its cooling and freshness properties through 50+ washes.

Our signature fabric is 66% Lenzing Modal, 29% mint-infused viscose, and 5% elastane. This blend gives you softness, stretch, cooling, and breathability all in one.

Yes. Our moisture-wicking comes from the natural breathable cellulosic fibers in the fabric — no chemical treatments needed. The structure of the fiber pulls sweat away from your skin naturally.

Most sleepwear is designed to look good, not to help anything. We built ours around a real problem: night sweats, postpartum overheating, and the kind of disrupted sleep that leaves you drenched and exhausted. Our mint-infused fabric delivers real cooling, moisture-wicking, and natural freshness — so you actually rest.

Fun fact: the scientific name for peppermint is Mentha piperita. We named the brand as a nod to our secret ingredient, with "Piper" also being a trending baby name — a fitting double meaning for a brand built for new moms.

Sleep sets include a matching top and bottom, sold together at a bundled price. If you prefer to mix and match, many of our styles are also available as individual pieces. Check each product listing for availability.

Yes — many of our customers start wearing piper & mint during pregnancy and continue postpartum. If you're in your third trimester or buying ahead, we recommend sizing up in the top for the most comfortable fit. Our nursing-friendly styles with built-in shelf bras and adjustable straps are especially popular for the postpartum stage.

Yes! Gift cards are available here and never expire. They're a great option if you're shopping for a new mom, a friend going through perimenopause, or anyone who deserves better sleep.

Generally, yes. Our styles are designed with a relaxed, comfortable fit. If you're between sizes, we recommend sizing up for a looser feel, or staying true to size if you prefer a closer fit. Check our size guide for detailed measurements.

They can. Our bottoms tend to run slightly generous thanks to the elastic waistband, so you may want to size down on bottoms if you prefer a more tailored fit. Tops are typically true to size with a relaxed silhouette — some styles have a slightly slimmer sleeve. When in doubt, check the measurements on the size guide.

If you're currently pregnant, we recommend sizing up in the top — especially in the third trimester — for the most comfortable fit. Postpartum, most customers find their pre-pregnancy size works well, though sizing up gives extra room during recovery. For nursing styles with our built-in shelf bra, the stretchy design accommodates changing sizes comfortably.

When in doubt, size up. Our relaxed fit means going up a size will still look intentional and feel comfortable. Still unsure? Email us at hello@piperandmint.com and we'll help you find the right fit.
